Same thing happened to me. If you check the Wi-Fi Diagnostics section you should see under UMA: Status: Phone not allowed on wireless. Could be because we don't have UMA (what ever they're calling it today) enabled on our account, or they don't support the 9700, or both.
Rogers can be pretty stupid sometimes.
My other Blackberry is a PlayBook.
188.8.131.522 was the OS that enabled UMA for Rogers 9700's.
At the end of August, Rogers locked out all phones that were not on one of their TalkSpot Plans.
I lost UMA access. I called Rogers up and got onto a $5 TalkSpot Access plan (not the $10 local unlimited nor the $15 Canada long distance). The $5 plan is not an option in MyRogers, so you have to phone and ask. The $5 plan does take minutes out of your bucket but basement coverage is my issue, not talk time, so I'm fine with that. T-Mo has it available for free (but of course uses minutes) just like Rogers users did before the end of August.
