For the last seven months, I have been dealing with Internet problems. However I finally found out why my wireless router has been disconnecting randomly.

Every time I enable WiFi on my HTC Android cellphone, the whole router disconnects and I lose Internet until I switch the WiFi off on my phone.

I don't understand why it is doing this – has this happened to you? How can I fix it?

Interesting, what router is it? I know of a similar case with an HTC Desire HD, and a D-Link router I believe. – Paul Nov 14 '11 at 11:39
Have you tried upgrading the firmware of the router? – LawrenceC Nov 14 '11 at 12:31
Hmm, I havent tried that its a AT&T 2WIRE [2701HG-B Gateway] and when I click "View available upgrades and options" It just says page can't be displayed? – wifiprobodude Nov 14 '11 at 20:19
Note that simply connecting a wifi client to a wifi router should never be enough to stop the router working. This is definitely a bug with the router even if the HTC client is messed up. If you can't find a firmware fix on the Pace/2Wire website then you might want to consider replacing it. – Paul Nov 15 '11 at 2:40
Does your phone have a mobile wifi hotspot feature enabled? – Ben Richards Jan 26 '12 at 18:52

Your cell phone is probably broadcasting on the same channel as your wireless network. The problem could possibly be fixed by changing the channel on your wireless router.

Hope this helps.

Having 2 devices broadcasting on the same channel should not be enough to cause a problem - indeed this is a very common occurrence, particularly when people setting up wifi devices are unfamiliar with the frequencies other devices in the same area are on, or when there are more WIFI devices then distinct channels (which I've seen) – davidgo Feb 7 at 19:48
