I actually developed a similar problem with an HTC 8x in the past (which I just accepted bc I knew it was a very problematic phone) but now im having a WiFi problem my 822 as well. I started noticing apps (especially 6tag) taking longer to load a few weeks ago while connected to WiFi. I have the same problem on other WiFi connections besides my home one and have tried deleting the network in my phone and reconnecting, but this didn't help. Some apps seems to still run fine, perhaps its just due to the amount of content to load. Anyone else had this slowing WiFi problem on their 822 or other windows phone and know a solution?
