It is possible, lets make sure the setting on the router are correct http://support.apple.com/kb/HT4199. How many ipads are having this issue? What do you mean surge? - upload speed increase or decreases. Also what is the normal upload speeds, download speeds and ping rate? So try to test again with window surface and ipad with speed test at same time.

Checked those settings. AP is a Cisco 1252AG. Radio in use is 2.4 setup for N. If you look at the screen shot above you can see how the upload goes for a bit, stops...goes for a bit, stops again.

I see it now, how many Ipads do you have and what type are they? Try troubleshooting on the ipad side with http://support.apple.com/kb/TS1398. Then backup, http://support.apple.com/kb/ht1766, and restore as new,http://support.apple.com/kb/ht1414. If the issue is not resolved that it must be ios 6 issue. Maybe you could call apple to see about compatibility.

I've tried two different 4th gen iPads (both 32Gb) and they both exhibit the same issue. I thought it might be an issue with encryption, so I tried it on the old WEP secured network and it behaves the same way. Seems to be an issue with Cisco/Linksys Access Points. Download speeds are not affected, and upload isn't super important right now so I'm going to wait til iOS7 comes out and if it is still an issue I'll contact Apple.
Thanks for your help.
