Hello,
I read all these questions and answers, great forum by the way!
It was good to read that more people share my frustration with my nearly brand new itouch (Dec-08). After google'ing "itouch no wi-fi" and finding many hits, this one one of them, and browsing and reading most of the hits, I could not see a single answer that indicates rootcause and solution.
I had the same no-wifi-problem for a long time before taking action and contacting Apple around 2 months ago. As still in warranty (1year), they replaced my itouch, on a process that end-to-end took about 5-7 working days.
The new one arrived on 14th July and was perfect, looked like a brand new one, although could be a refurb, don't know. Wifi was working perfect and no issues. I re-sync'ed all my 15GB of music, apps, etc, registered device etc and now, 1 month on from receiving it, wifi stopped working.
I did nothing wrong with it, I am very sure, because it has been only 1 month and I use it almost exclusively in my 1h10m jog every morning.
Could anybody help me please?
I don't want to send yet this other one back to Apple and wait another 5-7 working days for a replacement, and not have my itouch, especially because my main use is to listen to music, which is unaffected by lack of wifi.
My frustration is, i invested my time in this, and i am back to where i started... So same steps do not seem to be a wise choice...
I look forward to a reply... All the best!
Tina
