Hi all I have a Samsung Galaxy Ace but my Wifi is always not in range. I think the solution may have been at Google Helps:

Use WiFi driver re-installation Code *#*#526#*#*...Reinstall the firmware for Wifi. Try it on other Routers as well this is a common problem with Androids. as i see (seen in lot of forums people discussing Wifi problem of Androids) My cousin bought the same Handset and he is having same problem. If it doesn't help show it to your vendor from where you have brought it

I was wondering how do I use WiFi driver re-installation Code *#*#526#*#* ?

These are called dialer codes, so naturally try typing it into your Dialer as if it were a phone number. I just did it on my Vibrant and got this:

WlanTest Engineering Mode
Status...
Unloading Normal Driver and Loading Mfg Driver

Driver loading successful

Wow! Is this the usual way of installing things? –  Pacerier Jan 11 '12 at 5:05
    
@Pacerier I know some other things like touchscreen drivers might have similar codes, but in general you don't want to mess with drivers. Most of your installs will be apps, which certainly aren't done through dialer codes :P –  Matthew Read Jan 11 '12 at 5:07
    
Btw my Wifi still doesn't seem to be in range evne after installing the driver and restarting the device. Do you have any idea what may be causing the problem? –  Pacerier Jan 11 '12 at 5:40
    
@Pacerier Sorry, no. Have you tried it with multiple Wi-Fi networks? –  Matthew Read Jan 11 '12 at 5:51

I had the same problem on Galaxy Ace but I dialed *#526# and not ##526##. I don't know if it's the same thing. Have you also tried removing and renewing the wifi connection on your phone?
