iPhone 5 keep dropping wifi signal after some usage

[lunatic_tokyo]

As mention, is anyone experiencing the same issue as me. I know it's common but did anyone manage to resolve it? My phone is still under warranty but I am concern if upon exchange will the problem still be there, as it seem to be a common issue.
Does anyone know if there it is a batch issue or hardware problem. I am on the latest iOS update.

Any recommended solution for this wifi issue or best to go for a replacement.

Thanks in advance guys.

I had that problem after upgrading to latest firmware back in March. Went back to Singtel service and replaced with a new phone using 6.0.2. wifi back to normal.

Had experience wifi issue also. In my case, it is able to connect to 2.4Ghz band but unable to connect 5Ghz band and speedtest around 2-3Mbps even when next to router.

Got it change from M1 and now back to normal.
