Hi all, first post here. I apologize if I'm beating a dead horse with anything I'm about to explain. I'm just in continuous frustration after plenty of research and attempts and needed to state my specifics.

Thanks in advance for any tips or insight and for reading this lengthy post!

I had to buy a new router recently, I bought a Linksys WRT54G2 router version 1.5. I've had very minimal success with my Blackberry WiFi Internet connection (no data plan w/ T-Mobile), both through the standard hotspot browser and Opera Mini 4.2. I've tried plenty of reconfigurations of my router and setting changes to make the BB Internet work. I have no problem connecting to the router with my laptop.

Current settings...

I have updated to the latest/greatest firmware of the router - Ver.1.5.01 Build 8.

Mixed Wireless Network Mode (not B-only or G-only). I've tried just G-Only.

Wireless Channel 6 (I've tried channel 2 and 3).

Wireless SSID Broadcast is enabled (haen't ever tried to disable it)

WPA2 Personal Security, TKIP+AES Algorithms (have also used WEP and just AES Algorithm)

Disabled MAC Filtering (also have enabled it in the past)

I have not tried to restrict any Internet access to any source (separate item on my router from the MAC Filtering).

I have not messed with Gateway or Ports (yet) even though I've read something about them, specifically Ports 500 and 45? Or something similar.

Anything else I am failing to considering?

Have you looked at the Wi-Fi diagnostics on your device? Manage Connections -> Wi-Fi Options, Menu -> Wi-Fi Tools -> Wi-Fi Diagnostics.

You will also find there Site Survey, Ping and DNS Lookup. Very useful tools in working out problems. You haven't specified your Blackberry OS in your profile so it is difficult to be specific, but modern Blackberry OSs are designed to work with, and use Wi-Fi in conjunction with, a Blackberry Data Plan. You can use it without one, but it can be problematic as you are finding out.

Thanks for the response.

I've checked Wi-Fi diagonstics (Options > WiFi Connections > *WiFi profile name* (not the actual profile name obviosuly) > Wi-Fi Diagnostics). That's how I got to it, I'm assuming more/less we're on the same page there.

I have Blackberry OS 4.5.

I've also removed the battery several times.

Again I have had success twice in getting WiFi. The first time was the evening I bought the router on Sunday (just needed to get the MAC address settings proper), and the 2nd time was 2 days ago with just a battery removal.

The error I always get is UMA 004 which means it doesn't establish an IP/DNS connection at all (I think more/less).

I had no trouble at all connecting to my previous router via BlackBerry WiFi (before that router kicked the bucket this weekend).

I've also unplugged and reconfiguring my router from square-1.

My laptop has no trouble connecting.

I had a similar problem with my bold. Here's my solution. Hope it works.

Thannks.

Data Services for me is currently set to On, but I'm currently at work right now and have had no trouble connecting to my work's wireless router, don't know if those settings automatically change or get recognized like the WiFi profiles do when you get to their hotspots.

I'll give that a try when I get home this evenign.

The FAQ says to reboot the router for that error.
Wifi / UMA Error Codes - BlackBerryFAQ

Is the router set to automatic DHCP? Also if you can find a QOS setting and enable it, and try to prioritize the phone, it could be what's needed.

I'm seeing the same thing here with my Bold 9000 (running latest AT&T OS, 4.6.0.304). A couple of additional details:

1) I'm not an idiot, promise - I'm an IT guy, have been doing this for almost 20 years.

2) Was working fine before I swapped out my old failing access point (Linksys WAP54G).

3) Not working since switching to the WRT54G2.

4) Everything else in the house is still connecting fine - three different laptops, two TiVo HD units, two iPod touches, an iPhone 3GS, two Nintendo DSes, and a Nintendo Wii - all via the same WEP configuration I had on the old access point (yes, I hate to use WEP, but that's all that's supported on the DSes).

5) If I bring the old AP back online, the Bold still connects to it. Can't continue to use the old AP though, because it needs reset at least once a day.

6) The Bold also connects to a separate WPA WLAN I have in the house (via a router for work).

7) Same symptoms as previously described - the Bold successfully "connects" if I delete and recreate the Wi-Fi profile, but the Wi-Fi icon stays gray. Wi-Fi diagnostics seem to show everything O.K., successfully "Associated" and "Authenticated", "Network acquired", no "Authentication Failure Reason, showing the valid IP address I'd expect. Long story short there, everything appears to be working, except I have no IP connectivity and the indicator stays grayed out.

8) Also similar to the prior posts, I've seen it once or twice suddenly start working several minutes after turning Wi-Fi on. When it's working, I can ping the IP address from another device and when it isn't, well, I can't.

So... there seems to be some sort of incompatibility between the BlackBerry Wi-Fi provider and the Linksys WRT54G2. No idea if the problem lies with RIM or Linksys, though.
