Can't connect to BIS on wifi

I recently moved, and changed ISPs. Previously, I had a stabe WIFI connection at home, now I can't get one to save my life.

My new ISP is Comcast, and I'm still using the same router I was using before, the only thing I've changed on the router is the QoS settings to accommodate the higher bandwidth I have now. My 8520 connects to my router, and I get an IP address just fine, but I can't get a connection to the Blackberry network at all. Running the wifi diagnostics tool gives me this result;

Code:

---

Wi-Fi
Current Profile: (SSID name)
SSID: (SSID)
AP MAC Address: 08:10:74:79:22:74
Security Type: Passphrase(PSK)
Local IP Address: 192.168.1.104
Signal Level: -61 dBm
Connection Data Rate: 48 Mbps
Status: Network acquired

VPN
Current Profile: 
Concentrator Address: 
Contact:  N/A
Authentication: N/A
Secure Device IP: 
Status: VPN profile is not found.

BlackBerry Infrastructure
Connecting: Trying...
Authenticating router: N/A
Authenticating server: N/A

---

"Connecting" is always either "trying" or "failed", with the helpful reason of "error".

I'm using n 8530 with Willyboy's 7.2 hybrid, and I have a rosewill router flashed with DD-WRT.
I was using the same os and router with my old ISP and had no issues.


Any help would be greatly appreciated.

Did you update the DNS information in your router after the switch? That's all I can think of. I'm using Comcast with no problems, although I do use OpenDNS instead of Comcast's DNS.

Nope, I've been using OpenDNS ever since I bought the router.

I did connect once today for just a few seconds, then it went away again.

Seems like Comcast is blocking port 443. But before you go on a hotline and bash them for being ignorant bastards, test it.
Get on windows pc and open a command line.
Type "telnet" and the ip addresses you find for your BIS in
advanced options > Host Routing Table > Wifi
The command prompt window should show a flashing cursor and no error messages.

Or, are you using any other device between the Blackberry and Comcast's network that might have a firewall blocking everything (ie. a modem)?

Seems the problem resolves itself if I reboot the router, but it comes back after I reboot my blackberry. Never had this problem before, I've been using the same router with the same settings for a while and the problem started when I switched to Comcast.
