English Network/Internet

Hi everybody,

First time using openSUSE 12.1, and installed it on my HP 2530p with intel 5100 wireless. Network Manager show that wireless connected with my router but I couldn’t access to Internet (via browser, installation,…). I tried to search solution for this problem but found nothing.

Thank you so much for your support.

To debug this kind of problem, take the following steps:

  1. Use the command /sbin/ifconfig to verify that your wireless has gotten an IP
    number. If not, you have a problem with DHCP.

  2. If your interface does have an IP, try to ping your router. If the IP number
    is XXX.YYY.ZZZ.WWW, then the router will likely be at XXX.YYY.ZZZ.1. If that works,

  3. Try to ping the outside world with ‘ping -c 5 8.8.8.8’. If that fails, you
    probably have a routing problem. Pleast post the output of ‘/sbin/route -n’.

  4. If step 3 worked, then try ‘ping -c 5 www.samba.org’. If that works, your
    network is OK. If that fails, you have a DNS problem.

Report back how many of the above steps work.

  1. My wireless got IP 192.168.0.101, but it took longer than other laptop to connect my route. It showed speed 4MB/s and after 1 minute was 150 MB/s

  2. I tried to ping my IP 192.168.0.1 but failed. My other laptop run openSUSE 12.1 with broadcom wireless still work well.

  3. Failed, here is /sbin/route -n


Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.0.1     0.0.0.0         UG    0      0        0 wlan0

  1. Failed to ping -c 5 Samba - opening windows to a wider world. Tried with default DNS and 8.8.8.8 or openDSN 208.67.222.222 but nothing change.

I run my laptop with Live CD of Linux Minx 11 or 12, wireless worked well but same problem in case i tried Fedora 16.

I suspect you mean lower-case b, as in megabits per sec, not megabytes. All
connection rates are in bits, not bytes.

I have no idea why either 2 or 3 should fail with this routing table, unless the
wireless interface went off-line immediately after getting an IP address.

Check the dmesg output for clues.

Once step 2 failed, there is no possibility of anything else working.

Thanks so much for your support.

Maybe wireless setting of OS have conflict, i also tried to disable IPv6 support or using ifup but nothing change. Network manager showed connection but browser was still looking for “domain name” in status.

Any suggestion :frowning:
