Sony Ericsson Xperia Arc S Wi-Fi Problem
If you own a Sony Ericsson Xperia Arc or Sony Ericsson Xperia Arc S, you may have noticed that it constantly drops connection to your Wi-Fi at home.
The official Sony Ericsson support forums are full of posts from disgruntled owners, bemoaning the annoying problem.

Basically, the problem is your wi-fi router. It’s not broken or faulty, or defective in any way. But it’s the way your wi-fi router is set-up to transmit data - and you’re going to have to change it. You shouldn’t really have to - Sony are at fault!!!
These screengrabs are taken from my PC, running Windows 7, but the pertinent information applies to any operating system, whether Windows, Mac OS or Linux.
Firstly, find your router properties. In Windows, you need to go to "Network and Sharing Center." Just left-click on your connection icon in the toolbar to find the prompt to open it.
Click on "See full map."
Right-click on your router in the Network Map and choose "Management URL." This will open your default internet browser and take you inside the workings of the router.
All routers have a URL which will open in a browser window, allowing you to change the settings. You can bypass the earlier steps completely, if not using Windows and if you already know your router’s URL.
My Wi-Fi router is a cheap TP-Link TL-WR841N and the Management URL is simply http://192.168.1.1/ If you’re unsure of your router’s Management URL, Google the brand name and model number - the information will be out there. Once you have this URL, you can then enter it manually into your usual internet browser.
Your router will ask for a username and password. Unless you’ve changed it in the past, it’ll be a default username and password. The default for my router is just “admin” and “admin.” Again, Google your router’s details to find your log-in details for your model.
Before changing any of these settings, make a note of your existing settings or take screen-grabs, in case this doesn’t work for you, and you need to revert back to your existing settings!!!
Now, here’s the important bit…
Firstly, you need to find the settings for Channel Width. I can’t advise you where these settings will be in your router’s set-up menu; I can only advise what you need to look for! Whatever number the Channel Width is set to, change it to 20Mhz.
Next, you have to find the Beacon Interval of your particular router. This number may be anything between 40 and 1,000. The number may or may not be appended by “ms” for “milliseconds.” You may see the words “DSAP NULL LSAP” within the same menu.
What this setting actually does, is determine how often the router sends-out empty packet data. The router does this to maintain a connection with your connected equipment. Too low and you’ll constantly drop connection and too high and you’ll constantly drop connection!!! The value needs to be set at exactly 50. If there’s an option to change the DTIM Interval, ensure it is set at 1.
Once done, reboot your router. You’ll lose internet connection while it reboots, but if you still have no connection after a few minutes, turn-off the power to both your computer and router for a couple of minutes (at the wall sockets) then turn back on. Computers have a habit of “remembering” the last used configuration of hardware, and any change could make it seem that the hardware’s been removed, rather than changed. Disabling the power for a couple of minutes erases this “memory.”
Obviously, if you still don’t have an internet connection, log into your router and revert back to your earlier settings! Hopefully though, this has worked for you.
One you’re sure that your internet is working, delete your existing Wi-Fi connection on your Arc, by going to Settings / Wireless & Networks / Wi-Fi Settings then long-pressing on your existing Wi-Fi connection and choosing "Forget Network."
Then, simply re-add your home Wi-Fi network.
For good measure, download an app called Wifi Static from the Android Market. Do not install and run this until you’ve configured your router as above!
Click here to download Wifi Static…
Start-up the app and choose "Add Configuration."
The app will automatically configure your home Wi-Fi connection, so just save or “OK” to whatever configuration it throws-up on screen.
What the app does, is latch onto your saved connection while you’re in range. If you then visit a bar, café, friend’s home, or other Wi-Fi hotspot, the app won’t invoke and your Wi-Fi will act as it always has. No, I have no idea how it works - but it does.
Let me know if this has worked for you. It definitely worked for me!
