Hi All,
I cannot claim that I discovered this solution. It was posted in some Cisco forums. But this worked for me.
My problem was that I could never get consistent throughput with the Linksys E4200 router via WiFi with my Transformer Prime. Throughput would be good for a short period of time and then it would either stop or spit out bits and bytes in small chunks. This behavior was odd, and I had a hard time figuring out what was causing it. Because of the way it occurred, I didn't think it was a hardware problem, the way the GPS situation is.
I had thought a firmware fix from ASUS might resolve the problem. I think there is a problem with the ASUS driver software, but you also can resolve this problem by disabling QoS, specifically WMM, under the Gaming and Applications settings for the E4200. Most people can access these settings by using 192.168.1.1 to connect to their router or by using Cisco Connect and opening Advanced Settings.
Good luck. I hope this will help some of you. This may also work with other routers.

I cannot wait to get home to try this.
I have been playing around with both my E4200 and the prime for months and resolved that either my walls are made of lead or the prime/e4200 was rubbish.
Thanks man! I have the same router and this change definitely helped me out.
When you get ANY router always turn off that QOS/WISH type garbage. Anything that specs or touches your signal it will just slow it down.
Is QOS enabled by default on the e4200?
hope this change helps
I recently upgraded from the WRT54G to the Linksys e4200v2 and I have noticed that I have problems reconnecting to the wireless after extended period of tablet sleep. Turning off, then back on wireless on the tablet fixes the problem, but annoying no less. This change was immediately noticeable from the first time I joined the new network, no software/firmware updated at the time.
I looked at the v2 setting and under applications & gaming, QoS, there is a wireless area at the top of the settings page. The WMM support setting is enabled by default. I have set to disabled, I will see I'd there is a noticeable difference.
>you also can resolve this problem by disabling QoS, specifically WMM
http://www.smallnetbuilder.com/wireless/wireless-features/30938-dont-mess-with-wmm
"Since WMM support is required for products to be certified for 802.11n, WMM comes enabled by default in all Wi-Fi Certified n APs and wireless routers. So even if you don't have any WMM-aware devices on your network, leave WMM enabled or you may find your clients connecting only at 54 Mbps rates."
Not saying it doesn't do what the OP said, but you may want to run before/after throughput tests with your other devices.
bah didn't realise that fact that I'm on DDwrt so I probably don't have any Linksys firmware issue. Nonetheless disabling WMM did give me a boost of 2 or 3mbps
unfortunately the prime never syncs at higher than 54mbps
Most routers have QoS enabled by default. A long, LONG time ago, I bouted it out w/ Motorola because the issues I was having with one of their routers was found to be due to QoS.
However, all 15+ times they had me restore it to factory default, QoS was re-enabled, so their troubleshooting was counter-active to an issue they were causing from the get go.
The original firmware for the e4200 v1 is really rubbish. The signal was bad, speeds were fluctuating, the range was worse than with my 6 years old Belkin.
I tried numerous different settings, it was better but it still sucked...
Then i discovered Toastman's tomato firmware.
The flashing process is the same as with the original firmware (really simple).
I have used this firmware - http://www.4shared.com/file/KOjVG1Ge/tomato-E4200USB-NVRAM60K-12874.html?
But you can use other firmware from this link - http://www.4shared.com/dir/v1BuINP3/Toastman_Builds.html
!!!Just make sure that it has e4200 in it's filename.!!!!
Instructions for flashing are in the link below, in the third post
http://www.linksysinfo.org/index.php?threads/linksys-e4200-which-tomato-firmware.34493/
The configuration is easy - first you need to find the channel which works best for you in your enviroment, and i also enabled FRAMEBURST and set preamble to SHORT.
I now have a ultra stable connection, the speeds have tripled, and the range is superb.
Syslink should be ashamed that we need to flash custom firmware for their products to actually work:/

Thanks... was wondering if Tomato had been released for the e4200v1 yet... I'll be giving this a try later, as I've always herd good things about Tomato firmware.
Honesty lately, I've serisouly been considering getting the new Asus RT-N66U router. I like the fact that it has external antennas, & reviews have been great. Not to mention you can change its firmware out too, unlike the e4200v2, which uses hardware that does not allow for firmware changes.

I have an E2000 and an E3000, both running dd-wrt. In my case it's not WMM specifically, but a subset of that called "no acknowledgment". With that enabled none of my Android devices will stay connected.
As posted above, my experience is that I lose my n speeds the moment I disable WMM.

You do lose N speeds, but the throughput is far superior and enables you to download files more quickly as well as view hi def YouTube videos with vastly improved smoothness. At least that is my experience. YMMV, though.

I also have the E2000 but on the stock firmware so I was hoping to clarify your post. If I update the router to dd-wrt and disable no acknowledgment I might improve wireless on my Prime? does disabling this subset also limit throughput?

Well, with that setting enabled my prime refuses to stay connected to wifi...no ack is disabled by default in dd-wrt, i had onky enabled it to see what (if any) difference it would make.

Whats the password or default password. I have tried connecting, but none work. If you having problems with your Prime, its more of a antenna issue and you need to contact Asus to repair it. There should be a thread dealing with this issue.

Hey.
I just got myself a 201 yesterday and I already experienced some problems with my wifi.
I have a 3700 from NEtgear, so dual band wifi 2.4 and 5Ghz.
From the prime I can only see the 2.4 network... And even so, the wifi connectivity seems unstable. I often have to refresh stuff in browser or applications cause the connection dropped.
This is quite annoying. I'm fairly confident my network is working correctly cause I am using other device with it , among them, a galaxy tab and with those devices, I do not encounter such problems.
FYI I have the .21 firm already.
Prime only does 2.4ghz and there's been a big known issue with wifi. Don't be surprise when of your gps is also crap. Also try going through this section ( general) for all known issues a possibe fixes.
Honnetly i tried to browse the forum but there are so many information , and those even differ depending on the firm, it's not easy to get a clear pic.
What is the main pb with Wifi ?
Oh and I didn't know the wifi on the prime was limited to 2.4 band... That's odd.
Well i need to learn how to read the specifics

Honestly the 2.4 has better range than 5 anyway. Unless you are doing wifi file transfers it won't matter, but even at that it won't matter because with a cord it still takes a while for the memory to write. Basically you would gain NOTHING by using wifi because the memory writes slow. That being said the problem with the wifi dropping seems to have been mostly fixed with fw updates. Weak signal is thought to be due to the metallic back plate blocking the antenna from receiving a strong signal (same with gps). Other issue that could be affecting wifi is if you are streaming to bluetooth (ie headphones or file transfer) at the same time as using wifi which is a known issue as well.

Not really odd, its the norm and most tablets have only 2.4Ghz. As stated the 2.4Ghz has more range than the 5Ghz and will more readily transmit through walls. Yes 5Ghz has a higher data transfer rate but for the most part the 2.4Ghz transfer rates far exceed any current internet connection available. The only time it would be benificial is doing file transfers over wifi but then again the connection would be faster than the read write speeds. I find I get a better transfer rate over 2.4Ghz wifi than I do over USB but still dont use that often. Most of my mdeia resides on either the MicroSd or Sd card in the dock and I load data on those cards via my laptop with a USB3.0 reader which blows any other method out of the water by a long shot!

True, my ATP has serious wifi throughput/range issues on the latest firmware.
Hi Folks,
Had my TFP201 for about 4 weeks now (C3 preloaded with ICS 4.0.3.15)
Updated to .21 standard...
My WIFI has been VERY unstable compared to iPad/iPhone/PC's on the network...
Yesterday night i decided to have a go and changed my encryption settings on the AP from WPA/TKIP to WPA2 and "BOOM" !
My WIFI Signal and stability suddenly became strong like hell.... ( i could have up to 35/30 Mbit on the other side of the house..)
Have not had the time to see if this also have any impact on the WIFI/BT issue, but i will try to test this weekend...
So, to those with unstable WIFI : Try to play with WPA/WPA2 or even turn off
to see if this could be a part of the challenge....
This could very well be a router/AP related issue (I'm running on AVM 7390)
Interesting, ill try tonight when I get home....but ill proly have a few maker's marks sooooooo I'm sure someone will beat me to it

"This could very well be a router/AP related issue (I'm running on AVM 7390)"
I've noticed this and I think I've read it around here on XDA. I have a Cisco AP and when I'm connected with the my Prime it works flawlessly. I also have a Amped Wireless extender all my other wireless devices work great with it except my Prime. As soon as I start transferring files or stream anything it will run for a couple seconds / minutes then drop the wifi and reconnect. Perform the same process using the same files connected to the Cisco AP - flawless. While at work we only have Cisco AP's and NEVER have an issue with my Prime.
I believe the AP can / does make a difference.
Just so you guys are all aware, the only encryption you should use for wireless n is WPA2 with AES.
Anything else and it generally falls back to g speeds.
Also, if your router had a setting for WMM, and "no acknowledgment" having the no ack setting on can cause wifi issues for some devices (my i9000 and wife's iPhone, and my prime drop wifi, for example)

I also have an amped wireless extender. Using it as an extender posed no problems for me besides cutting bandwidth in half which is normal. Using it as an access point negates that issue easily. I have my regular access point and just changed it to suggested setting so I'll see if it does anything.
WPA2/AES is faster and also more secure than WPA2/TKIP. TKIP generally had broader support on older equipment, but it's hard to find new devices that won't support AES. I've seen TKIP used in combination with various certificate and authentication protocols for large networks, but for home use, stick to AES.
Hi,
Love the phone, but the wifi is so bad it is ridiculous. First of all, I always have to do *#0011# to disable wifi saver otherwise is it completely unusable.
But even then, it randomly disconnects. Seems this device is simply unable to deal with many APs or many networks. It is completely useless for VOIP because of this.
Is this going to plague this phone always? Meaning: is this something that can be fixed by custom roms and or kernels (I know samsung will prolly never fix)? Or is it simply the hardware that is badly designed and will always suffer from this?
FWIW this is not a universal problem. I usually flash a new custom ROM version about once a week to keep up with the latest ICS firmwares, and have never had any wi-fi connection issues. I'm often on 2 wi-fi networks throughout the day (one at home and one at work). I've never done the *#0011# trick or anything like that.

I do wonder if it is hardware related then...
My understanding was that this is very related to the routers. All my APs are running dd-wrt. Very annoying to see my iphone and ipad never having these issues whereas my daily driver (the s3) is pretty flaky. Maybe someday there will be a true fix!
No issues here either. Have a multi AP setup at home and work with upwards ten SSIDs at work. Mostly g/n networks. 2.4 and 5GHz works equally well. No problems anywhere, not even in town at cafes or my parents crappy Thomson all in one ADSL modem/router.
Using AOSP but Sammy original worked fine also during the first and only hour of use.

Did you update your phone? The update fixed my issues with WiFi and haven't had to enter the screen since, and yes WiFi is really good now
Dude, my s3 wifi adapter is very good. you should analyze your wifi AP and see who is sharing your channel frequency . Most people use same channel 6 by default. Channel 1 is the least used IMO and it's clean. If 1 and 6 are often used then use 11.

My main APs are on ch1 and ch11. Other networks are far away (no interference, and signal is pretty clear.)
To clarify: when I do the 0011 trick, my wifi is pretty stable, but disconnects from time to time making it too risky for me to get on a VOIP call for fear of disconnection. Speed is great though. And every once in a while, it will simply not switch correctly between my two networks (one in house, one in garage), it gets stuck on 'getting ip'. I then disable wifi and reenable, which fixes it. (thank god for WiFi Manager Premium's widget)
It is not unlivable, mind you, but it is pretty crazy annoying. Especially when ALL other wifi devices I have never have any issues.
Will try a full stock reset when JB comes out officially, that always seems to help in the many wifi threads I've read in the forums thus far.
this fixed my wifi problems when I was getting very slow speeds in the last few JB leaks

I will certainly give LH2 a try then. I had (wrongly) read that the post-LG8 updates didn't seem to change a whole lot.
I recently had all kinds of strange problems with my phone. Charging slowly.. wifi was terrible. The rom i was running made no difference.
In the end i was going to send it back as i thought i had faulty hardware. The day i was to get it sent off.. i thought what the heck.. ill try a .pit file to force a full repartition. And its only gone n worked!
Phone is back to running how it should.
I would be VERY careful flashing .pit files tho... is always a last resort.

Hi,
I had exactly the same problems with wifi like the OP! My S3 was always either not connecting nor finding networks. Sometimes it worked and then the phone was loosing wifi all few seconds... reconnecting. Using skype was not possible!
Above that, pressing power-off to send S3 to sleep was not responding everytime... sometimes the screen stayed on but touchscreen was not responsive. Then power-on again it was not responsive, too.
So a lot of problems with a device at this high price...
After nearly 2 weeks I've sent it back and got a new one. Now everything works perfectly!
Both devices were updated to newest update LG8.
If it is a software problem, there is maybe something going wrong while updating, otherwise I would say it's an hardware issue.
Good luck!
I don't know the topology of your home network or equipment. But routing with Nat, and two different network using the same private ip address range could cause issues. Again I have no idea what's up with your network. Are you running a essid or two different networks?

Doubt it, simple enough setup. One main, one wired AP (both on same SSID) and a repeater bridge for garage, diff SSID. No problems with the laptops, apple devices, etc.
Will test out every kind of wipe/flash... I fear exchanging it will be hard seeing as this is an unlocked international version bought in Canada online.

Hi,
I am running NT 16gb CM10 with 0.06 build from chrmhoffman. I am consistently having my wifi dropped in couple routers, but my home router (older) seems to stay connected all the time. The signal was strong before connection in all cases, but in the dropped wifi cases, the signal drops to less then a bar after connected, and it would only connect for couple minutes at a time and drop off. Any suggestions? I have installed wifi fixer, but no help.
From his post:

Is the above potential compatibility fixes apply here? If so, which file should i amend?

I had trouble with the wifi, too.
When you upgrade to the later images, be sure to format /storage first. That fixed my problem.
CM10 wifi drop offs consistently
I have the same problem with every CM10 ROM I've tried, even the newest SGT7+CM10+Cherry Picks,By meghd00t released 11/24. (only drops about every 5 min or so, which is better than any other cm10 ROM I've tried) I've managed to trace the problem back to the router, for some reason CM10 causes it to randomly reboot. I'm assuming this is either because of the European region code that can't be changed or a driver issue causing a loop-back fault in the older routers. I'm using a NT8gb with a D-Link DIR-655 rev.A router.
Only suggestion I can offer is to buy a new router that plays nice with CM10.
P.S. I've read in other forums that a lot of people are having the same issue with android devices running JB

I'm assuming this is either because of the European region code that can't be changed or a driver issue causing a loop-back fault in the older routers. I'm using a NT8gb with a D-Link DIR-655 rev.A router.
Only suggestion I can offer is to buy a new router that plays nice with CM10.
P.S. I've read in other forums that a lot of people are having the same issue with android devices running JB

Instead of buying a new router you could try loading DD-WRT or Tomato firmwares. That is if your router supports it.

I read somewhere about a user setting to keep Wi-Fi alive somewhere in advanced options. Might be worth looking into.

It's a router issue not a device issue. Setting WiFi to "keep alive" won't fix the router cycling.

Workaround
After a few days of research I've found a few workarounds. Apparently my router was made with insufficient RAM and the chipset doesn't support DD-WRT.
Option 1:
Partition the wifi in advanced wireless settings. Router still cycles but it only cycles the partition that the nook is on.
Option 2:
Enable the guest zone and have the nook connect using the guest wifi. Same effect as partitioning the wifi, but only reduces internet speeds by 50%.
Option 3 (Best option):
Downgrade to the lowest possible firmware you can get your hands on. (in my case 1.11) Wifi still drops on nook, but not as frequently and it doesn't seem to cycle every connection on the router every time the nook drops. (You'll want to use a firmware with Draft N protocols instead of N protocols)
This works on DIR-655 rev. A routers, not sure if it'll help anyone else who's router doesn't support wireless N 5Ghz.
Got my hands on firmware 1.02 shortly after I wrote the above, network stability is a million times better now.
I hoped this issue was resolved but its not. Its a device issue not a router problem for me at least. Anyone have any ideas

Found an answer in http://forum.xda-developers.com/showthread.php?t=1952141&page=25
Wireless N 2.4GHz has issues with the current CM10 builds, switch to 5GHz if your router supports it or turn off wireless N
Upgraded my router back to latest firmware to test this out, disabled wireless N (switched to G only mode), worked like a charm
I have the same problem, it seems to be a CM10 issue. I've chaged several times of rom and even changed my router but didn't help. Maybe rojasc is right, I will try that!
