I have a problem I’ve never heard of before, and had no success finding any other discussions about: my wireless connection works on some networks, but others it never even finds. They don’t show up in Network Manager, or when I use iwlist.
Some details about my system: I installed OpenSUSE 13.1 x86_64 on my Dell 1440 laptop, using a fresh install via the DVD, multi-booted with Win7 and an older version of OpenSUSE (12.1 I think). All updates applied by selecting update all packages if newer version available in YaST software manager. Currently using Linux 3.11.10-7-desktop.
I installed and then got updates with the ethernet connected. Upon finding the wireless didn’t work I checked dmesg and ran /usr/sbin/install_bcm43xx_firmware as indicated there. Then the wireless seemed to work fine…until I went home (where I have no ethernet) and found that my wireless there is not recognized. I’ve restarted multiple times (also due to chasing down an issue with my printer which is still unresolved, may post later on that) and double-checked that the wireless is in fact working.
The only wireless I have at home is from my Droid X running pdanet+. I booted into the older version of OpenSUSE which I had (thankfully) left intact and verified that I could get on the network; here is the output of iwlist from there (showing the phone’s wireless):
Cell 04 - Address: 40:FC:89:71:4B:5C Channel:6 Frequency:2.437 GHz (Channel 6) Quality=70/70 Signal level=-27 dBm Encryption key:on ESSID:"asl_droid_ff" Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s 9 Mb/s; 12 Mb/s; 18 Mb/s Bit Rates:24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s Mode:Master Extra:tsf=00000000803db1e5
But when I boot into the new system, iwlist never shows the phone wireless. I tried my wife’s phone, also a Droid X with the same setup, with the same results - works fine with another OS but cannot be seen when running 13.1. But at work, with some old D-Link wireless router, I can get on just fine (that’s what I’m using right now). Both networks are set to WPA2, neither one hidden. Tried entering the phone wireless SSID as a hidden network (which it is not) with no results. As I continued to fiddle around further I noticed that occasionally on the D-Link wireless it does randomly disconnect. I can still see the network listed when I click the Network Manager icon, and when I click on it, it quickly reconnects.
Here is some info on my wireless card:
$lspci -vnn -d 14e4: 0c:00.0 Network controller : Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01) Subsystem: Dell Wireless 1397 WLAN Mini-Card [1028:000c] Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f69fc000 (64-bit, non-prefetchable) [size=16] Capabilities:  Power Management version 3 Capabilities:  Vendor Specific Information: Len=78 <?> Capabilities: [e8] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [d0] Express Endpoint, MSI 00 Capabilities:  Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities:  Device Serial Number xxxxxxxxxxxxxxxx Capabilities: [16c] Power Budgeting <?> Kernel driver in use: b43-pci-bridge Kernel modules: ssb
As I write this I am sitting next to both the D-Link and the phone (with wireless turned on), and can see both of them from the Win7 laptop sitting next to me, and have verified both on the older version of OpenSUSE on this same laptop as noted above. Why can I not see and connect to the wireless from my phone using OpenSUSE 13.1?
Thanks for any help you can give.[/size]
