Hi guys, I've been having trouble with my home router since i got a smartphone (xperia active).
I've had my current router for over two years, have the desktop wired to it and a laptop which uses wireless, and never had any particular issues. Eversince my phone got on the wireless network this causes the router to lockup in random and unpredictable ways. I've done a lot of searching on the web and found tons of people reporting wireless issues using multiple devices on home network, especially with tablets (KF in particular) but none gives a solution to the problem. The router is running fw from a USR9108, i never had problems with friends coming over for lan sessions or general browsing and never skipped a beat with up to 4 devices connected at the same time (no smartphones).
Since the phone came along i've been suffering from random wireless lockups, sometimes 3 in a day, sometimes once in a week, which require a hard reboot to get internet access back (once wifi is gone also eth loses connectivity)
Desktop (eth) + phone = no problem
Desktop (eth) + laptop (wifi) = no problem
Laptop + phone = wireless lockup
I tried switching wifi channel, giving the laptop and pc a static ip and making custom routing tables, i have removed anything which could cause overload of requests, double checked all dhcp settings, but all to no avail. After browsing a while leds on the router become static and the wireless one turns off. I've read somewhere it might be related to ipv6...
Has anyone got some suggestions I could try out before trashing the router for another one (with no gurantee this will solve the problem?)
Thanks for any advice
Try flashing your router using OpenWrt, DdWrt, Tomato or similar firmware, if your vendors software is buggy.

I got my HTC Hero on Orange in the UK last week.
I am getting an issue where a normally stable wireless network will be knocked out if i connect the Hero on Wifi.
I know its not the radio - connects fine on WEP secured work network and on the open connection on the train and at McDs
I have done a fair bit of googling and RTFM and basically found lots of router specific issues on Android phones but nothing that looks like the same issue i have encountered except one on the Android community forum where no one has a solution or suggestion i havent already tried.
XDA developers was a great help with unlocking and flashing a ROM to my Trion so i thought i would amend the post i made there and see if i get any more expert opinion on here. Apologies for the length of the post - will post ROM and build numbers if that helps (and someone tells me where to look on the phone!)
Conscious this is a lenghty post (hello all!) but thought as i struggled to find anything it might help others in the same situation if i detail the issues and what i have looked at and hypothesised that i need to try to resolve this - in case anyone else has similar issues.
Netgear DGFV338 ADSL and Ethernet VPN & Firewall router.
Three wireless laptops and Sony Ericsson G900 all connect fine
Laptops run XP Pro, Windows 7 RC and a dual boot Vista/Ubuntu machine
desktops (all on gigabit backbone) run similar mix but only lose internet after router and modem have borked.
I am running this on a 20 MB Virgin connection which is usually faultless (3 years or so uptime not counting upgrades to the modem). Speed or timeout is not an issue - usually get between 12MB and 17MB DL and 700kbps UL
As soon as i connect with the Hero i can use the Wifi but briefly (one web page, start to load Market etc) - basically network detected and WPA-PSK TKIP connected, IP allocated and showing in wireless clients table of router.
I was running restricted MAC access and IP/MAC binding as i have ports open for the 360's and the Wii and want to restrict access to these devices only but removed this as part of the troubleshooting.
Shortly afterwards 20 seconds to 1 minute after connection the wifi drops - all connections lost, laptops lose connections and i lose connection to Virgin. It requires a full reboot of modem and router with the Hero off to recover a connection.
I wiped the router and all the security and all the other pcs etc work fine
then turn on hero - same story. So its not any of my more esoteric and paranoid router settings - i dont think.
Been on the Netgear forums and apart from some issues with the G1 and AES on home routers (mine is the full enterprise kit metal case) i find nada
Troubleshooting to date has narrowed it down to a couple of choices.
I know my router but i am brand new to this phone so some of this is pure guess work. One suggestion was ARP floods from multiple requests from phone getting it blocked by the firewall. Except traffic logs dont support this
Encryption support:
I use WPA PSK TKIP - this is detected as WPA Personal by the Hero but it can connect to router when i use the pass and this setting so i am working on the basis this is supported and correct.
I have read about issues with poor AES support on some routers which are fixed by a firmware update but have the same issue with other devices on AES so would prefer TKIP. So it could be encryption handling - initial connection works but error logging could crash the router if this is not working correctly
Anybody know if the WPA personal listed for connections is TKIP or AES?
I cant find any clear information on this.
Orange DNS or restricted gateway settings:
This appears to be the main symptom - i lose DNS support and therefore access to the internet. Turning off the Hero and reconnecting the laptop gives me access to the router but i need to reboot the modem to get my IP back (dynamic but changes every 12 months or so) the hypothesis is that the Orange connection in this build has the DNS hardcoded to go through their DNS servers which either Orange or Virgin systems dont like and boots my connection off the internet. Bit of a long shot but as i cant seem to find any way to fix static IP or DNS listings it could be the case as i cant switch to OpenDNS as i would to test this otherwise.
Only comes to mind as the first day with the phone (when Orange 3G was not active) i didnt have this problem - wifi on phone and laptop worked fine and both together
Bit of a longshot but the symptoms point to a DNS corruption if it isnt my router treating repeated WPA or DNS requests as a DOS attack. It could be DHCP creating errors but i can bind a MAC to specific IP to override this on the router. It sees the Hero, recognises the MAC and adds it to the restriction whitelist.
I havent checked ARP logging but that theory could pan out as its unlikely DNS would take down the router and modem - ARP or DOS lockdown could.
WiFi Channel
I run channel 11 due to neighbours wifi interference - Wii wont work at all with default channel.
I cant find the default channel information on the Hero but would assume it is 6 like most devices.
this one is strange - if it is the Wifi Channel then seeing the router should be a problem and connection shouldnt happen at all. It seems unusual to allow a connection but then crash the router as it is getting traffic on a different channel.
Could be another side effect of my routers firewall blocking suspicious traffic but seems unlikely.
As you can see a fair amount of things have been tried and i am still getting nowhere.
I need to try the encryption settings - does anyone know what the WPA setting is on the Hero and which encryption is supported/offered as standard?
I need to try changing my router back to channel 6 - does anyone know the default channel or how to change this in the Hero?
I need to try static rather than DHCP (but on the phone as already have tried forcing IP from router) - how do i get to these settings?
I need to try static DNS rather than Dynamic (router proxy of Virgin DNS)
I do have a Linksys WRT54g (three of them - one vanilla, one Sveasoft and one Tomato) which i use for outside events at work so i could swap one of those in but i suspect its a combination of Hero settings and router settings and i would like to get my main router set up (and keep the 8 ports) than swap back to the older WRTs and have to set up my Xbox 360s to get around the issue they have with being on a switch with a different subnet and not connecting to Windows 7 media centre
Basically i have tried most of the things i can try with the access i have on the phone and my knowledge of its default settings. What apps can i try to give me control of the networking and access section?
Otherwise, loving the phone. Better than the reviews and whilst not lightning fast its a damn sight quicker than an overclocked Trion i was running before (which worked fine on the same router and WPA Personal)
I am liking Android, glad to not be locked into the Apple tax/ecosystem and realising that WinMo has a looong way to come; even with the help HTC and xda developers offer to make better use of the hardware.
But i am heavy internet user and i cannot risk running my Hero at home on 3g when i have 500MB cap and a £3 a MB over limit charge with no notice from Orange to say i am near limits.
Any ideas? feedback? similar tales of woe?
Possible solution
Ohkaaay - found advanced settings so that helped! n00b error
Removed all security.
Changed channel to 6
connects
change to channel 11
connects but crashes router
reboot router and modem
change back to channel 6
change security to WPA Personal AES
connects
doesnt crash router
change to channel 11
connects
doesnt crash router
i appear to have a working connection and there is no way i would have made it through this post with the Hero on before i made these changes
weirdly i now have two identical entries in the wireless networks list
one says SSID_name Connected
two says SSID_name WPA Personal
remove remembered networks
Hero autodetects my SSID_name
sign in with AES password
two listings in wifi list again, same as before.
So it looks like WPA TKIP doesnt work on my router with Hero
AES does.
Channel 6 works with no security
Channel 11 doesnt
BUT... enable AES and Channel 11 works.
Guess the Channel 6 signal issue interferes with the TKIP or something
But i can report that on Netgear router WPA Personal AES works ok, which apparently on the pre-Cupcake G1 was a known issue.
Apologies to post and then reply to my own post but this might help someone
I can confirm your findings regarding WPA + TKIP vs WPA2 + AES.
I was running WPA + TKIP on a Linksys WRT54GX and experienced major connectivity issues with my Hero (although is did not crash the router). Did not experience this problem with my iPhone 3G.
Changed configuration to WPA2 + AES and Hero does now work without any issues.
I know this:
A. Is fairly obvious
and
B. Is not particularly helpful to you
However - if any device (regardless of whether it is buggy or not) is crashing your router, the router clearly has buggy firmware itself and is at fault. Router firmware should be robust to the unexpected, especially on wifi as this could be prone to denial of service attacks from anyone happening to be walking by. A router that is crashed by an attempted client connecting is a bad sign.
My personal advice would be to change to a decent standalone router. I use a Buffalo WHR-G54S flashed with Tomato firmware v1.21.8005 (with a seperate linksys Adsl2+ modem to provide internet). It is working flawlessly for me in WPA + TKIP/AES with no issues.
hello
i was so looking forward to getting my new x10 mini pro only to find a few faults some of which i can live with until 2.1 comes out (should really be 2.2 & sooner) but i cannt seem to connect to my wireless router.
i have tried several different methods, including going through all the wireless channels on the router, enable mac address filter and have only my x10 set, try all the differents security settings - but still i cannot get my phone to obtain an ip address before it gives me the unsuccessful message.
so went to mcdonalds tried their openzone and connected fine to their network.
now my next guess would be is my router is old (about 4 years maybe more) linksys WRT54GS so anyone know of any problems with specific routers at all?
i know i had problems setting up my godsons ipod touch with my router, but didnt dig any deeper on it as he wasnt fussed about it at the time - so think it could be that but will hold off rushing out to get a new router for a while yet, probably to test some other peoples routers first.
Is you SSID hidden?
I have found that on some routers, Android phones in general won't connect if the SSID is hidden.

The WRT54GS should be a perfect router to use.
Make sure you are running latest dd-wrt firmware on it, setup wifi security as : WPA2 Personal Mixed, TKIP+AES
I have these settings and phone connects easily.
Its a good router, do as above poster advised and definitely get latest firmware on. Try going on just G mode if there's no B-only old wifi gadgets in your house.
Sent from my U20i using XDA App
I noticed my wife's X10 mini won't connect to Channels 12 and 13. If your router is on one of those channels, try moving it to 11.
I have difficulties connecting to my wifi router at home, SMC Barricade N2, WPA2 authentication, it works only after resetting the router.
Now after turning off TKIP cypher suite (only AES), it works perfectly
update: and also helped to enable static IP... but I am using wifi only @home
Had the same problem. Changed to Channels 11 and detected imediatly my wifi network.
Hi, I have a different problem with the wifi.
At work and some other connections I've seen to have an open wifi, which i can freely connect.
However, I am still unable to browse the internet as it requires some browser authentication.
I've seen other fones (Nokia and Iphone) have their browsers popup a webpage to input the credentials.
but my mini pro doesn't display this page.
i've already tried going directly to the login url manually but still doesn't display the login page.
someone told me that this might be a limitation of android but haven't seen any reports about it...
i also saw and tried 2 apps (Open Wifi Login and Browser Wifi Login) that should have solved this but did not.
Has anyone else had this experience?
Help please....
shameless self-bump
other fones seem to have the same issue but no solution...

Hi guys, so here's the deal : Just got a brand new Optimus One and the Wifi dosen't really work. It took me ages to get it to detect my home network ( Realtek RTL8187, used as a hotspot via win7's wireless miniport adapter - so basically virtual hotspot) Once I managed to get a connection the device would either be stuck at "obtaining ip adress from..." or would simply disconnect and reconnect in a quick burst. I finally managed to get it to connect by manually assigning the internet sharing permissions for the virtual miniport, but the speed is abysmal! We're talking to the order of bytes/s, measured both by attempting a small download from the phone and by reading the in/out data on the pc connection info. Upon some further poking around, a few wifi adapter and phone restarts later, I notice that when I connect to my hotspot the phone's wifi manager reports a normal speed of 54mb/s, but when I actually try to use the connection (say, the youtube app) it works fine for a second or two (it usually loads a bit of a vid, or half of a big webpage) and then drops down to the aforementioned speed and the phone's wifi manager indicated that the connection is 2mb/s
Also, I went out before setting up my home network to a mall and tried to connect to one of the free hotspots available. On some, it would connect straight away, but be very slow (signal wasn't great) and on one (max signal) it would disconnect/reconnect in very short bursts (10-15 times a minute) and it would eventually establish the connection. Then the same speed issue as above: works fine for a few seconds, drops down to unusable. Didn't think about checking the connection speed there, simply thought the public network was overused. In hindsight, the problems were similar to the ones experienced at home
A few side notes: The 3g speed is fine, consistent and problem-free
I have tried changing my home wifi's frequency to a number of settings (there are quite a few other wifi's around, I know it could cause issues if they overlap)
My wifi connection was actually not detected by a friend's laptop wifi, but we could connect our computers just fine via ad-hoc (which from what I've heard is a no-go with android at the moment - and the phone does not see ad-hoc)
The phone is brand new, only installed a handfull of apps on it, didn't change any relevant settings (I think)
Set wifi sleep policy to "never"
My pc wireless adapter worked just fine in the past, used it for a few months as the main internet connection, and even with half-signal it would achieve good speed. I also moved the antenna away from the PC itself to avoid interference
I set my PC to use only 802.11b since I've read around that some phones prefer this to 802.11b/g
That's about all I can think of right now. (oh, and It's my first android, so I don't know my way around the OS that great yet)
I appreciate any advice you can give me. Basically I'm trying to find out if it's an issue with my Wifi adapter, it's settings, the phone's settings, or if the phone itself might be broken, so I can send it back to warranty.
Thanks in advance.
Try switching from b to g.
it was initially on b/g
Hey everyone, I got myself a Z2 recently and have been very happy about it for the most part. However, some things seem to not function a 100% the way it's supposed to.
Some times after it's been to sleep and I try browsing online with it using either 3g/4g or wifi the phone says it has a connection, but nothing loads. All I have to do to solve this is to refresh the wifi/3g connection manually, and then it works. It's rather annoying to always go through that procedure every time I want to use my phone, so I'm wondering is there anything I can do about this? Or anyone experienced anything similar?

I have the same issue with WiFi while the phone sleeps or is active (no probs with mobile data though!), but I was not able to determine whether it's my router, the phone, or a combination of the two (though I have a hunch).
When I'm in my room which is unfortunately the farthest from the router, and the connection drops, my Z2 is not able to reconnect on its own. Have to disable/enable WiFi or else it's stuck in an infinite loop of connecting and obtaining an IP.
Now, I'm fine with a dropping connection occasionally given the distance and the... quality of my router. However, my laptop is able to reconnect automatically.
I have tried lots of possible solutions: WiFi sleep policy, static IP or DHCP, disabling/enabling WiFi optimisation or Auto-IP, switching WiFi channels, and various WiFi fixer apps. Nothing worked.
My guess? There is a bug in the stock firmware that makes the phone unable to reconnect if a connection is forcibly dropped . Pair this with a crappy router and you have a recipe for inconvenience.
Unfortunately, I have no spare router to confirm this, and with the bugs in CyanogenMod I am reluctant to flash for now.
Also, I am sure this is not a hardware fault of the phone in my case since I notice this behaviour at home in my network only.
Do you guys possibly know where I could find some logs related WiFi? I wanna get to the bottom of this.
So, I got my S9+ (international version, DUOS, 256 GB) last week from the Samsung store. I am on stock ROM (and will stay as long as my warranty lasts or someone finds a way to root with Knox 0x0, which I am not expecting).
At home, I have a WLAN Mesh (AVM Fritz!Box 6590 Cable, 2x AVM Fritz! 1750E Repeater on a wired connection), everything working great with any device.
Except my S9+. It connects and everything is fine, at some point - especially when using it for e.g. streaming Netflix or so - it will stay connected to the WLAN but will say "no internet access". Switching WLAN on and off fixes the issue until it happens the next time (minutes to hours later). I have no special settings, no neighbouring networks which would interfere. I have 2,4 and 5 GHz active and automatic channel selection. All other devices in my home work with no problems. I have found similar issues froim users on other Samsung phones (S6/7/8 series (my former S5 on Resurrection Remix Oreo does not show t his behaviour)), but no answers that worked (like forget the network, reboot and reenter credentials).
Quite annoying, anyone knows a fix? Big THANKS in advance.
No one experiencing the same thing or havin any ideas?
I have had the same issue in the beginning with the phone. I have a router with a cisco switch connected to it. The standard router's wifi wasn't sufficient in coverage through my house. I got hold of a cisco AP and connected it to the switch and disabled the wifi on the router. That's when my issue started. Fiddled around trying various options, but the one that worked for me was to tell the phone to forget my network, restart the phone and then "setup" the wifi on the phone again(password for wifi needed to be entered as it sees the network as a new one) Haven't had the issue after that. I did notice at my office that even though the wifi conection is good, that if it goes below a certain percentage, the mobile data will kick in, although I have that option switched off. I also picked up that if your line connection's speed goes very low for whatever reason, the same problem appears again that the phone assumes there is no internet
Thanks, this is what I've read from other threads (with S7, S8), too. But this didn't work for me. My repeaters get ther signal through LAN cable and I have a fast connection, coverage all over my house and garden. I really do not have an idea on what to try...
