I wiped my device clean via phone and reinstalled the software via Nokiasuite, and now have an issue with my wifi connection.
Its seems as though its not working 1 in 20 chance a webpage opens (but weather, twitter,facebook feeds refresh).

The connections is strong. At first I thought I fried my wifi due to some overclock play but I guess not.
Conky shows that download speeds are 0.1-0.7kbs.
Do I need to flash the phone the normal way for fix this?

Cheers

reboot helps?

Reboot doesnt help. I changed the housing to see if that helped, but no.
When I change connections from one to the other, I get a page to load when the connection is happening but then its stops.
It took like 2h for skype to connect on wifi, even longer for some other apps.

Just a simple suggestion?

It seems like a similar issue I had a few months back after a flash. I'm not sure what could have triggered it, but, definitely one AP wouldn't work at all which was fine with other phones (even another N9). I didn't mind it back then as that was not the default connection I use to connect to internet. After a recent flash, when I tried with the same AP, that was totally fine the problem was rectified.

Would a 'restore settings'help? Not sure.

I tried everything except a true pc flash. Was kinda hoping not to do that but looks like I might not have a choice.

Try to set wi-fi power saving to medium. It always helped me for slow connection.

Tried that too, ehh. Gonna have to reflash it again

I have similar problems where the connection is very slow for most of the websites. And some sites(google, YouTube, etc) work fine.
So what i do as a workaround is open a terminal and ping google.com and let it run in the background, then everything works fine.

I also cant download maps for drive, or check out warehouse for example. Need to do everything on my carriers connection. The only thing I can do on my wifi is update feeds and catch a gps signal faster :P
