Wireless problem "Network is unreachable"

English Network/Internet
1

Hi all - complete n00b here I’m afraid! Trying to see if I could switch over to Linux & making a slow start …

I tried following the stickys in this Forum and have some info as follows:

“Getting Your Wireless to Work”

II:
YaST hardware information:
Model: Intel Wireless WiFi Link 5100
Driver: iwlagn
Kernel Driver: iwlagn
Bus: PCI

III:
I don’t seem to have a boot.msg file (is the post out-of-date or should I have one?), but dmesg | grep firmware provided:

13.482638] iwlagn 0000:04:00.0: loaded firmware version 8.83.5.1 build 33692

IV:
iwlist scan:
Looked similar to expected, although got several “IE: Unknown: 2D1A7C…” entries?

VI:
iwconfig output looks pretty much as per the example except:
Fragment thr:off
Link Quality=70/70
Invalid misc:32

VII:
ifconfig looks fine to me
pinging my AP is fine
ping -c 5 66.70.73.150 returns:
connect: Network is unreachable

“My Wireless Doesn’t Work”

b)
lspci:
04:00.0 Network controller: Intel Corporation WiFi Link 5100

lspci -n:
04:00.0 0280: 8086:4232

dmesg | less
driver found and firmware loaded successfully

“Welcome”

I’m using the ‘traditional “ifup” method’ and I don’t see any connection strength icon on screen. I can’t tell what version of OpenSUSE I’m using but it was downloaded fairly recently (a couple of weeks ago?). I’ve tried Network Manager first and seemed to get very sporadic connections (up for a few seconds only).

Erm … help?![/size]

oS 12.1 in systemd mode doesn’t have that file; the contents go to
/var/log/messages instead. What you did using dmesg is a correct workaround.

Then your connection is up, but your routing is not. Perhaps you have not
set a gateway.

There is none with that method.

Sorted! Many thanks Carlos - I’m sure that’s trivial to those who know but I was really stuck … and now I’m in business. Thanks again!
