Here is what I'm experiencing: My network connection will work fine for a while after a reboot, and then suddenly all of my queries will timeout. Sometimes I'll get a little bit of data through but it's just a trickle if anything. If I turn wifi off and back on again it will work, sometimes for a minute sometimes longer, but it eventually drops out again.
I've tried a few things that I've picked up on the forum but haven't been able to get anything to work yet. My wired connection seems to be OK. Can anyone provide some guidance for how to troubleshoot this? I've not had a lot of experience with unix/linux configuration so I'm bumbling about a bit. Thanks!
