Iphone 4 WIFI signal keeps dropping.

Thank you for helping me fix my issue with my IPhone dropping wifi.

Resetting the Network Settings is the only solution that has helped me.

Settings > General > Reset > Reset Network Settings

To all having problems with their iPhone keeps disconnecting on their wifi at home, try to change your Wifi Channel Settings on your router, usually its on automatic change it to channel 9, this is what I did to fix my iPhone wifi disconnecting problem.

I am only having this issue with my son's iPhone 4s. Everything is fine on my iPhone 5, my other son's iPhone 4s and 3 other iPhones - just his. Any suggestions other than changing my router settings? 5 out of 6 don't have an issue. I hope I don't have to take it back to Apple.

I have found a workaround to this:

Settings -> General -> Cellular -> Cellular Data - set this to OFF

This forces the iPhone to always use WiFi for data rather than periodically dropping the WiFi connection to use the phone network instead. You'll want to switch this back on again when you leave your house or WiFi area.

This is not a fix - Apple need to address the bug - but since doing this my iPhone WiFi connection has been rock solid whereas before it would drop constantly throughout the day.

The downside is that the phone won't receive picture/MMS messages via the phone network until this is re-enabled.

Hope this helps - certainly made my days less frustrating!

Strangely I have found something out today gone to settings - general - scroll down to auto lock set that to never and password lock/ restrictions to off and my iPhone never dropped the wifi off all day. The wifi only drops out when some sort of lock or password setting is on...

Instead of renaming my network, I have found that telling the phone to "forget this network" restarting the phone, reconnecting to the netowrk (password and all) works.

I find this issue very frustrating!

I didn't want to rename my network (not at this time anyway) and since I don't have issues with anything else using the network, including my iPad mini, I didn't feel it was necessary (yet). I have tried jazzmoose's suggestion and so far it works for me. I don't have a problem turning Cellular Data off when I am home. I hope Apple fixes this issue with their next release!

I am having the same issue- on Iphone 4s, on IOS 6.1.3 so it says up to date, have tried all work arounds and nothing is working for me 😟

Just tried this solution, renamed SSID and changed from channel 6 to 11. Reconnected right away and staying on for now. thanks for help. I guess the new SSID gets the iphone to reinitialise its settings and that does the trick. I am guessing IOS upgrades force a review of network settings to make work OK. Seem this type of issue before on other Apple devices.

Thanks again

None of the mentioned solutions seem to work for me, iphone4s, constantly dropping my home wifi, really frustrating since my wife's iphone5 working ok as is our iPad , no signal drop,,, but seems to be holding so far since I've tried it with activating my VPN app on my iphone and that's going on 20 mins without a signal drop, prior to that it was dropping every 30 seconds or so until I switched off/on wifi in settings each time
