Hi. I'm having problems with internet. I finally got openSUSE 13.1 (UEFI) up and running (took me only 6 days!!) and I am very new to Linux and have no idea what I'm doing. I am on a Lenovo G780 laptop with the following internet thingies:
01:00.0 Ethernet controller : Qualcomm Atheros AR8162 Fast Ethernet [1969:1090] (rev 08)
Subsystem: Lenovo Device [17aa:3979]
Kernel driver in use: alx
Kernel modules: alx
02:00.0 Network controller : Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)
Subsystem: Broadcom Corporation Device [14e4:0587]
Kernel driver in use: bcma-pci-bridge
Kernel modules: bcma
Now, here are the two problems I am having:
The wired internet works out-of-the-box... but only sort-of. It randomly stops responding (sometimes lasts many minutes, sometimes stops after just a few seconds!) It will say that it is connected to Wired Connection 1 in the Network Connections thing, but it will not ping anything and can't go to webpage or whatever. If I unplug the cable and plug it back in, it will reset and work fine. The problem is not the cable coming loose or whatever -- it works 100% of the time in Windows 8 and I have never had this problem in Windows, even when I knock the cable around on accident.
The second problem is that the wireless doesn't seem to work at all. I don't think it's fully supported yet, though. But it seems like it could potentially work. I mean, it realizes the hardware is there. And now and then (usually about 20-30 minutes after starting the OS), in the Network Connections, it will actually pick up my wireless router! The connection name will appear and I have the option to connect to it. If I connect to it, it will say it's configuring for a little bit, and then change back to "Not connected" under the WLAN interface. I have also set it up completely manually in the Network Settings to no avail. Usually when I do a scan, it does not even recognize the connection is available (in fact, in picks up NO connections, whereas in Windows I get about 15 different connections to choose from when I'm sitting in this room).
But anyway, since it does sometimes detect the connection, though rare, and only for a minute or so, I feel like it's close to working and there must be something I can do to get it working.
I saw on a compatibility list that similar adapters/chipsets need b43 firmware to function, but I have no idea what that means, or how to get it/apply it to my system. So I tried googling that and found another page that said that b43 firmware is not compatible with my exact setup anyway (http://wireless.kernel.org/en/users/Drivers/b43
) and alternative is brcm80211. Well, that's great, I guess, but I still don't know what that means or how I can use that knowledge to help me. I don't know how to change a firmware or install things or really do much of ANYTHING in Linux.
Also, I should note that despite being able to go to web pages, whenever I try to do something else with internet connection (like search for updates or whatever from within a software), nothing seems to happen. It just seems to hang at the searching part. This is of course with the wired connection, because the wireless doesn't work at all.
So, for a complete noob who has no idea how to Linux (and not particularly that well-versed in computers), what should I be looking for/trying at this point? Everything works 100% in Windows 8 of course.
