Trouble communicating with router DHCP?

Question

my home network is has problems regarding linux computers, two ubuntu and two mint. I have had a look at the log files and searched the internet regarding the solution. I cannot find a whisker of a solution. One of the mint computers connects fine, the other three appear have this same problem. A PS3, Mac and all Windows connect fine.

I've tried:

• Disabling IPv6 (I don't think my router is IPv6 friendly)
• Using USB wlan device, internal WLAN device, and and Ethernet cable (all this work on other networks/windows)

So I suspect this is a problem with my computer(s) not being able to communicate with my router in a common language. But I'm not much of an expert. I hope someone will care to look at my log file I believe the answer is in here.

If I can add anything else which may help the diagnosis please add a comment.

Answer 1

Well I can answer the question 50% now, since purchasing a new router the problem has dissipated. But I cannot explain why x of the computers were incompatible.
