Greetings all
Have an issue with my wireless.
It sometimes doesn’t connect to my wireless. And sometimes when it does it gives me an invalid IP address.
I have a lenovo SL400 Laptop. Intel 802.11agn wireless is my adaptor. And I have OpenSuse 11.4 with gnome.
I works fine if I give it a static IP Address but that will create an issue with other computers on the network.
Is my desktop environment (GNOME) or is my Wireless adpator not compatible with opensuse.
Any Ideas?
Post the result of
/sbin/lspci -nnk
This will tell us exactly what device you have. Put the output in code tags please.
LAN IP Addresses shouldn’t really make any difference, unless you have other settings misconfigured in the router.
For example, all my devices connect to my access point and each has a single specified LAN IP by reservation based on the device MAC
But I can just as easily switch that off and allow access by DHCP to a LAN range, but I loose individual control that way.
Are you using “ifup” or are you using NetworkManager?

I am using something called Network Connections that came preinstalled. I don’t know whether that is Network Manager.
Your device:

Is OK. With the correct driver in place.
If you can explain this comment:
It works fine if I give it a static IP Address but that will create an issue with other computers on the network.
Perhaps we will better understand your situation.
I have no problems with the wireless if I give a computer a static IP address. But by doing so can create IP address conflicts with my family’s computers.
That’s really not explaining yourself
Do you mean a LAN IP?
Normally, the WiFi router has a range of IP addresses that it will use with DHCP. However, the full subnet is typically larger.
For example, one of my routers uses a subnet 192.168.1.* (192.168.1.1 to 192.168.1.254). It only gives out IP addresses 192.168.1.1 to 192.168.1.50.
The trick with a static IP, is to assign an IP that is outside that DHCP range, but still in the subnet. When I was using that router, I assigned my desktop the address 192.168.1.100.
My current router allows me to reserve IP addresses for a particular MAC address, which is an even easier solution.
In an earlier post in this thread, I asked if you were using “ifup” or “networkmanager”. The reason I asked, is because “ifup” typically used “dhcpcd” for DHCP queries, while “networkmanager” uses “dhclient”. In my experience, it is best to use “dhclient” with wireless.
Thanks Nrickert
I shall give that a try and see how I go. I have a feeling that my router doesn’t work well with linux. When I had Windows 7 installed, it worked with no problems.
caf4926 - Yes I meant LAN IP. I am also a newbie.

Extremely unlikely
What router is it?
Its a NetComm 11n Wireless ADSL2+ Router
I wanted to try and look at the router
Routers: NetComm
But couldn’t decide if yours is in the list
NetComm 11n Wireless ADSL2+
Its here:
OK
So it’s OS independent. Which means it’ll work no problem.
I downloaded the manual.
I suggest you use a set range and assign a specific IP to each MAC
I shall give that I go the next time it plays up.
