Hi friends. I am brand new to Linux and openSUSE so please bear with me if I say anything stupid 
I have been using Windows all my life and even though I thought I knew a lot about computers, I really just knew a lot about using Windows.
Anyway, here is my setup:
01:00.0 Ethernet controller [0200]: 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 [0280]: 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
I am having problems with both my wired and wireless connections. I am mostly concerned about the wireless since I almost never will use wired anyway.
I installed openSUSE 13.1 KDE from the LiveDVD and am now dual-booting with Windows 8. I can get a connection with wired, but it constantly ācuts outā (says it is connected, but get no ping from sites, etc.). If I unplug the ethernet cable and plug it back in to the laptop, it works again, but will eventually stop working (usually lasts 1-2 minutes at the most, sometimes cuts out in a few seconds).
But about the wireless:
I have extracted the b43 firmware from the device using the firmware cutter, Iāve downloaded all the b43 and broadcom stuff I can find, and tried all combinations of modprobe this and that (though I have no idea what I am doing at all. People just give me lists of commands without explaining what they do. I can kinda guess, butā¦ really Iām clueless) to try to get something working. No dice.
It seems to recognize my hardware just fine. I can set up my internet settings and search for access points. When I scan for access points, I find nothing (even though normally I can find about 10-15 different ones from the same spot on the couch in my dadās house, and about 4 or 5 from my house, and a dozen or so at my friends ā I have tried at many locations). Now and then though ā like maybe once an hour, for a 3 or 4 minute period ā I will see my router appear in the list! It will be the only access point. Iāve completely set it up ā I know how to at least manually configure the access point. But it will not connect. It will start to, and then fail at some point during the connection, and just kind of disappear. After a couple minutes, the access point will disappear as if thereās nothing there.
At my house, my husband keeps the router sitting on a desk (everywhere else itās on some shelf or something and difficult to reach), and I was able to set the laptop literally touching the router (so the hardware was within 1 foot of each other). The access point was always found, and I could connect to it, but I would constantly get disconnected (every few seconds).
So, itās not that the wireless is completely not working, but Iām getting extremely weak signals and canāt keep a connection. Itās similar to what happens with the wired connection, but a lot more fickle and must be RIGHT NEXT to the router.
Looking at this list hardware-driver compatibility (or something; I donāt even really know what any of this means, just general idea):
It says that my specific PCI-ID (14e4:4727) is not supported with use of b43 and b43legacy (but is WIP). It suggests the broadcom driver, which I am pretty sure I have successfully installed.
I experience the same problem with many routers, ethernet cables, ISPs, etc. All the same problem, so it is not a problem with the external hardware.
When I boot Windows 8, I am able to get a 100% reliable connection both wired and wirelessly from long distances from the router.
I have been trying to figure this out for over a month now on my own, have asked on other topics, and this is my last stop. If you guys canāt help me, I think I am going to give up on Linux and just be a Windows user permanently. This is way too stressful and frustrating. I love everything else about openSUSE so far, but I NEED a reliable internet connection. I canāt just reboot the computer into Windows 8 every time I want to look at a web page, or constantly reconnect to a router while standing over a desk so I can be right next to it over the course of 15 minutes to download 500 KB of data when Iām getting 3MB/s download speeds in Windows. Iāve been spoiled by internet being reliable and fast and canāt revert to the frustrations I had with shoddy dial-up in the mid-90s.
Please help me 
I donāt want to be a Windows-only guy anymore
To see more of my complaining about this, hereās my thread on another forum that eventually died:
Wireless not working properly (broadcom, opensuse 13.1)
I figured since this forum is openSUSE-specific, I might be able to get more detailed help, even though it seems like a Linux problem. I havenāt been able to try any other distros because Iām also having a graphics problem, and openSUSE is the only distro that works for me.
