dear all,
if there's anything that i hate then its unreplied posts at LQ, especially when they're mine
don't really know why i didn't have this problem earlier when my router was still windows 2000, if somebody can explain i'm more than happy to hear about it.
in the meanwhile the problem is solved bij changing the dns to static, nameserver 1 + 2 to 4.2.2.3 and 4.2.2.2 on both the router and the suse desktops, (it didn't had something to do with IPV6 in this case), and now my browsing flies like it should again.
case closed!
