Broadcom 4312 dying? AKA No buffer space available
Posted by anjilslaire on May 22, 2009
My Mini 9 appears to have suffered a grievous internal wound; perhaps requiring surgery. A few weeks ago, the wireless started acting up. It seems to connect to my router fine, and signal strength is solid.
However, after about 5-10 minutes, sometimes quicker, all traffic dies. Network Manager reports that i”m still connected, with great signal strength, but all ping attempts to my router result in:
ping: sendmsg: No buffer space available
At first, I suspected it was overheating, as the mini has no fan or other moving parts, so I left it on a cold stone floor. No real change. I did some searching, and found that in previous releases this was discovered and fixed with a kernel update in backports. However, I’m running the Jaunty 9.04 UNR release, and the Broadcom wireless has been working fine since I’ve had the machine in December. This has me truly stumped, and I”ve submitted my own bug report on Launchpad. Hopefully someone smarter than I will come to my rescue.
If not, then I may just have to buy an intel 3945 Mini PCI wireless card to replace it. It appears they are not too expensive, and my Inspiron 1420 runs flawlessly.
Until then, my Mini is stranded 😦
