I haven't been able to prove or disprove this yet, but it seems that when I connect to my home wireless network, the phone seems to crash the network. Laptops, TV, etc everything else seems to lose network connectivity. Then I switch off the WiFi on the phone and a few mins later, everything connects again. It happened about 5 times last night, and already once this evening. However I've now been connected for almost an hour with no problems now. Normally my network is up 99.8%, so the day I come home with the new phone and it crashes that many times, makes me think...
UPDATE..... I updated my D-link router firmware.....the first time since getting it in 2008...we'll see if that helps.
UPDATE 2.... Router firmware update didn't prevent the next crash... It crashed again....now seemingly it's only happened when using Twitter.....and I don't tweet....just read local happenings.
