Is there a setting to tell the RAZR (or possibly any Ginger ROM) when to switch from AP to AP in the same wifi network?
For example, when you have multiple access points and you initially enable the wifi radio, it'll connect to the strongest signal for that network. But if you move out of range (or on the edge of range) of that AP, but are in-range of another AP for the same network, the RAZR does not switch AP's...it just keeps trying to connect to the "far" AP, even though there is another AP with a much stronger signal (closer).
The only way I could get it to switch to the new AP was to toggle the wifi radio off and back on, then it would immediately connect to the closer/stronger AP.
So I'm looking for some kind of setting that (maybe) says, "if the connected network's db falls below some signal strength, see if there are other APs for the same network -- based on SSID -- with better signal strength and connect to it." Or at least a setting where if signal is lost completely, don't rely on just searching and connecting back to the same AP for that network, see if there are any closer.
I realize that if you do not have WDS running, it could cause a disruption in your connection, because each AP will try and give you a new IP address, but it's a lot better than the "retry with futility even if you're out of range" situation I have now.
Thanks,
AJ

That exact same scenario worked fine for me last Friday in the office. I have an European RAZR, not the Droid RAZR and we have literally dozends of WiFi networks at work and when I moved down from the second floor to the first floor it automatically switched to the AP with the best reception and back, when I moved back to the office.

Following on from my investigations on why the SGS2 takes *so" long to re-establish a WiFi connection, it now seems part of the problem is a major delay in obtaining an IP address.
In another thread (I forget which one) it was suggested that slow WiFi could be caused by a router not being able to cope with 802.11b, g & n traffic at the same time, which got me thinking - what if I disable the n part of the WiFi on the phone to revert it to 802.11g - would this make acquisition time on an older router faster?
So - does anyone know which file / script etc. could be altered to keep WiFi enabled, but ONLY at 802.11g; not utilising 802.11n?

Just a guess, but is likely a build.prop tweak
Is this a frequent problem ? Has never happend here
Sent from my GT-I9100 using XDA App
As I've said in my post on the general forum, I get a horrible delay every time I ask the phone to connect WiFi.
I've got the WiFi sleep policy set to "when screen turns off" to save battery power; and using the same router as on my SGS (hell, i can sit the phones next to each other to try this) I get the following:
Waking the SGS up from a sleep results in a delay of 1 or 2 seconds before WiFi connects.
Doing the same with the SGS2 results in a delay of up to 1 minute before WiFi will connect. (sometimes it can be seen to give up trying to acquire an IP address, then try again)
...so yes, may be a router issue, but clearly there's something different between the 2.3.3. on the SGS versus the 2.3.3 on the SGS2 as well.
You could just disable n mode on your router if you think mixed mode is slowing it down. Most new routers will let you choose which wifi modes to broadcast via their web interface. The best option would be to only use n if all your devices support n.

Router only supports g. I'm suspecting the phone looks to n first, hence my interest in disabling it.

quick side note, wifi sleep policy set to NEVER saves you much more battery power because when it switches over to 3g, 3g uses way more power than just leaving it on wifi. counter intuitive but true.
Have you tried hard coding an IP address on the S2?
And by Hard coding, he means manually setting a Static IP address and now allowing the DHCP to provide you an IP address each time. Although the IP will most likely be the same while using DHCP, it has to request and authenticate each time. Setting a Static IP address eliminates the process of "Asking" for a IP address each time.
when the phone scans and finds the ssid, as part of that scan it checks if the router supports b/g/n then will try to connect at the highest speed. If the router isnt n compatible it wont even try.
I don't want to give the phone a static IP as I regularly visit three or four different wireless networks and they don't all use the same IP range.
I do know how DHCP works, this isn't a newbie question.
It seems definite now, watching the phone, that it tries to connect once (presumably on n), fails, then re-connects (quickly) on g.
Of course, I'll be changing the router eventually; I'm just interested in what's going on first

Understand about leaving it set for DHCP. Trying a fixed IP as a test may tell you if DHCP is part of the delay. If the b/g/n search is that slow it would be useful if it could be configured more precisely.
Have you tried it using another router using only g? If n is available it connects quickly? Seems like others would have mentioned this if it is something with the phone as g-only networks are still common.
I too am interested in disabling 802.11n. wpa_supplicant keeps hanging on some wifi networks and I suspect it may be because of n.
Hi,
I've tried disabling WIFI powermode (which I do everytime I reboot), but my wifi seems pretty flaky. Speed is great, but it sometimes disconnects (not THAT often).
I have two APs, both set on same channel / SSIDs etc. Looking at wifi analyzer, it seems like the phone doesn't really handle switching between APs very well.
Is there a kernel or mod that would help with that? Or perhaps a better way to set my APs? (DD-WRT and Tomato, all 2.4G). Should I try the modems or is that just for cell network performance?
Especially annoying when using Talkatone or Skype to phone someone and then it drops in the middle of a call.
Thank you!
Setting to AP's within range of each other to the same frequency is asking for trouble.
Having them both broadcast the same SSID more so.
The kernel handles Wifi-related stuff, modem is only for cell communication.
Wifi has no handover protocol such as 2G/3G/4G does, so you'll stay connected to an AP until you loose the connection and then reconnect through the whole connection protocol (including Handshake, Authentication, DHCP, ...) on the next one. So it's a pretty bad protocol for moving around with a constant data stream.
I was under the impression I HAD to have them use the same SSID since this AP is there to extend the range of my home wifi (as per: dd-wrt WAP website I can't post link to since I'm a noob), I'll try setting them to channels 1&11 see if it gets better...
I had issues at work. But not at home.
Today I told it to forget my B/G radio and to connect to the N radio. No disconnects, none..
No changes made to the phone at all..
Hello team,
My Samsung Galaxy S3 GT-I9300 (international version) started to have wifi problems after stock update to 4.1.2. After that, I´ve tried many software and hardware fixes, including changing the wifi antenna cable. The result was the same, so I decided to try custom ROMs and came straight to CM11.
The wifi signal is very weak, and I can only connect from a few meters from the router
Installed CM11, full wipe cache/data/dalvik and still the same problem, weak wifi, connection only from if close to the wireless router.
Reading all the forums on XDA and CyanogenMod, I found the wifi-fix patch, which writes "murata" on the /data/.cid.info. This fix brought me powerful wireless signal, and now I get full signal bar to my router and even see many neighbor APs... but I am not able to connect. When I try to connect, type de password and than it just goes back to "Saved, protected by WPA/WPA2". I´ve also disabled authentication on the wireless router, and the result is the same. It won't connect not even to open networks, although I see strong signal.
Deleted the wifi_fix patch (delete ¨91fixwifi¨ on init.d, delete ¨.cid.info¨ under /data and rebooting), and went back to old status: very weak wifi signal, but able to connect (associate) if I´m very close to the router.
Turned wifi on and off, airplane on and off, captured log on "Murata" and "Samsung" modes...
Strange is that my wlan mac address is 88:32:9b:xx:xx:xx, which seems to be Samsung, but the Murata brings me powerful signal (although I cannot connect).
Well, I´ve tried many solutions so far, but that´s how far I could go...
Can anyone provide me some clue to solve it? I would be very thankful to have wifi back to my phone.
Log files are in attachment
Murata log (strong wifi, not able to connect)
Samsung log (weak wifi, able to connect when very close to wireless router)
Thank you all!
I too have only a range of 3 metres, I have 7 routers in the house because of this, yet I have less than 15% coverage of the house with this device. To put that in perspective, an HTC One X and Atrix 2 has 90% coverage with 2 routers. I'm 1 metre from the router in my room and I've got 1 bar, sometimes 2 briefly.
[Edit]
Woah, I tried the fix from:
http://forum.xda-developers.com/galaxy-s3/help/cm9-i9300-advice-t1898004/post41394293
Seeing as it can easily be reverted, it displays very high signal. What I'd expect. But it doesn't let me connect either. I also tried CM10.1 like the people who it worked for, it didn't work.
Just switched from cable to VZ gigabit FIOS internet only. They require you to keep their router in the loop no matter what other devices you might add. Using Fios Router with wifi turned off, connected to Netgear Orbi with two satellites. Mumimo and Beamforming are off at the recommendations of several Fios/Orbi users. Connection is from Fios router lan to internet port on Orbi. I have two satellites because apartment is long and thin with many very thick walls.
LG V10 which works very well but because of location, has to get cell signal from another state across a river. Therefore I use it in wifi mode when at home. When in the middle of a phone call I often lose the call as I move close to another access point (or satellite for Orbi). Have tried SWIFI but it needs each access point to have a "different ID" and I'm not sure what they're referring to. Can't often hold connection. Also tried Wifi Switcher (Cloudie), Wifi Toggle and one or two others.
Suggestions for other apps to try, or other settings? I need to use the router because the cell tower is so far away and I'd really like not to have to stay in one place if possible. Thanks for any and all help.
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...
