IOS6 WIFI bug, still not work now, exhausted,help...

Question

Been like this a week now, tried every possiable way still not any help at all, it can connect the wifi, internet works for 1or 2 minuts then will faile again, changed one router and tried all different settings as still not work, someone told me they don't have this problem they are using different router,maybe it's because IOS6 have sort of confict with some brand router? I am using TPlink, should I keep invest different router and try? Or should I wait for bug fixed?
Apple didn't give any suggestion to customer and time schedule for bug fixed, this is really **** me off...
I will try to visit apple store to check if they can change a new one with IOS5 for me.

They will not change you back to iOS 5. I asked.
I spent almost 1 week trying to resolve this. Reboot the ipad, reboot my router, delete the network, rejoin the network. Nothing seems to work. I called the Apple support, spent 2 days. After trying every single solution (that I've already done before calling.. duhhh)..
They told me to:
- Go to iTunes.Back up all your data, transfer all purchases to your computer. Of course when I tried to transfer all my purchases, they stuck for hours, then crash everything. I had to redo this 3 times. HOURS!!!
- Restore your iPad from your iTunes. It will erase everything in your iPad, then start fresh as new
- Turn off your iPad
- Turn off your router, give it 10-15 minutes, turn on your router
- Turn on your iPad, join the network
Even though finally it looks ok. I am still going to return this iPad and get a replacement. I just don't feel confident with the device anymore. I just bought my iPad less than 3 months, still got the box. The support told me I could swap my iPad, all I need is to see the Apple Genius. So I made appointment, otherwise the Genius won't see you.
I got tons of questions again from the Genius. He said it is my router problem. Basically, I have a crappy router that came from my internet provider. He said that since they opened the store, he only knew TWO people came in with WIFI issue. I told him, all my other devices connect just fine... but of course, they're "oranges" not Apple.
I thought I'll be getting my replacement right away, but no.. Genius had to place an order first, and they will call me again, and I have to make another appointment to pick it up. I wonder why they don't have one in stock. It's the NEW iPad!!! I hope they're not getting my replacement from some kinda refurbished factory.
This is my first purchase with Apple. So far it is not a pleasant experience.
