Network connecting issues/annoyances

zKarp · #1 29th February 2012, 02:05 AM

*Is there anyway to display the current drivers that are being in Linux? Google search only return lspci or lsusb. Thanks in advance.

I'm currently using Fedora 16 and I'm experiencing some connectivity issues with my netbook. It seems to take a long time for my network devices to connect with the network and register a handshake, full connection or whatever technical term there is. I don't have any technical or detailed times of connectivity but I can supply some information below. It seems to have more of an issue after wake and on first boot(from cold startup) but don't let this statement disregard any ideas solely on this since It does have an issue something from just unplugging the Ethernet cord and reconnecting or turning the wireless off then back on.

I do know there is some is issues with broadcom 43xx wireless cards, but after trying multiple distros, after getting linux to pick it up, it worked flawlessly. However I never used the other distros as much or as long as I have with Fedora 16. (I was in search of a good distro for netbooks that allowed customizing while still community driven support for issues and availability of software while giving good battery life and performance.

Also there is an issue with this model with the hardware address of the Ethernet card and something that causes kernel panics if in the boot order, network boot isn't first. I already have this done.

Sometimes I get a kernel issue, not panic, but Automatic Bug Reporting Tool will capture various problems with the kernel during this time. One report is about compat-wireless driver and other is sch_generic. The reports are included as an attachment and posted on pastebin. compact-wireles link; sch_generic link.

**Not sure if related but yum seems to take awhile to check if the repo list is synced with the local.

Thanks and sorry for the large info which might be unnecessary. Just like giving as much details and experiences as possible so the solution can be found faster rather then a series of question and answer posts.

lsmod will list the drivers loaded, but it always requires a bit of research to figure out what is what. The WiFi devices are special. They usually use teenie little ARM processors and need to load their code from the PC host. So if your driver is bad, then you can sometimes get a new one from a Windows driver using a special tool to strip out the embedded code.

One thing you can do to get a faster initial handshake is right click the NetworkManager icon, Edit Connections, Wireless tab, select your wireless connection and hit Edit. On the ipv6 settings tab change the Method to Ignore. (The F16 default is set for Automatic).

To see which kernel drivers are in use, try running lspci with the -k option.
