T60 Sierra Wireless 5720 EVDO Woes
Posted: Sun Jan 24, 2010 2:44 pm
I have been using my T60 (Windows XP) with its built in MC5720 EVDO Rev 1.1 for 4 years without a problem except I was unable to ever update the MC7520 PRL. So I updated the MC5720 driver and Access Connections and the PRL update worked fine. But the new driver introduced all sorts of instability with the inability to reconnect after coming back from standby, and worse, blue screens a couple of times a day. I tried falling back but I can't find a combination of MC7520 & AC versions that either works or doesn't have the same problems.
I've read the massive "x6X BIOS device Whitelist" discussion. It looks like my best hope might be to ditch the MC5720 for a newer device, obtain a patched BIOS, newer EVDO device & drivers. I'd like to stay with a Lenovo-branded wireless device to maintain AC integration.
I'm looking for some guidance here from anyone who's been here.
Will going to a MC5725 get me a more recent and stable device driver?
Are there any other newer, Lenovo-branded EVDO cards that will work in a T60 (w/BIOS patch) that might promise better stability and throughput? Any FRUs that work or ones to avoid?
Or is there some magic combination of MC750 driver and AC that will allow me to keep the MC5720?
