I was having issues with my older Linksys wireless router and decided to upgrade to a Linksys E3000. However, after upgrading, I still have the same issues.
What happens is that I will be connected on my laptop (via wireless) and suddenly my connection will be dropped. Nothing I do seems to allow me to connect. My wife's laptop does the same thing. Wired connections have no issue, and if I give the laptops static IPs I have no issue.
I looked at the log in the web interface and get the following lines repeated when I try to connect:
Sun, 10 Oct 2010 16:18:08 received DISCOVER from 00:21:00:3B:D7:70 Sun, 10 Oct 2010 16:18:09 sending OFFER to 255.255.255.255 with 192.168.1.136
It looks like the router is trying to offer my laptop an IP, but the laptop does not take it. I verified that this is the MAC address of my laptop. I also do not understand why the IP that it is trying to assign is so high. My IP range is from 192.168.1.100 - 150 and I only have a a few devices connected.
I ran a capture using wireshark, but I don't really know what to look for.
