Hellow, I have troubels with internet, on different Linux x64 systems on my laptop(Lenovo ThinkPad sl510), but if I load WindowsPE all is OK :(( what coud it be? where to search?
There is an hardwere firewall/nat/gateway in my local network, it allows only connections to dst ports tcp 80 (http), udp 53 (dns) and no frags, no icmp, deny in and etc. But Windows Internet (the same Firefox) works fine :), and under Linux sites doesn’t loding full or “connetion timed out”…
But if I have can start downloading any file it would be downloaded full (I have downloaded DVD iso of SuSe)
Dns throu nslookup responce not evry time…
Decreasing of MTU to 1372 didn’t help :((( Deactivating ip v6 also…
What coud it be? What is different betwin Windows and Linux in DNS clients is any alternative dns client in SuSe? Is the trouble only in DNS?
It is readable, with a bit of effort…but it would get a lot easier to read, if you used a browser with spell checking.
It is unlikely that it is x64; are you using wireless or a wired connection?

You should only need http/https for general browsing, so it probably doesn’t matter that I don’t know what you mean by ‘frags’ (do you mean that you see no fragmented packets in dmesg/firewall logs? which? or something else?).

So, if it starts, ftp is working all the way through and every time without issues?

…or dig… when it is not working, can you ping your router? If not, what is the error message?
If your router is 192.168.0.1
ping 192.168.0.1
ought to give you a response. The response time ought to be low, and it shouldn’t drop packets, if left running for a while.
If you get the ‘network unavailable’ message, the handshake between the router and your computer has not been successful, and you have not acquired an ip address via mdns/dhcp. As a work-around, you could try giving it an appropriate (unused, and in the same sub-net) address manually, to see whether that brings it to life.
if packets are dropped it could be wireless at the edge of range (sometimes happens with the wrong driver) or an intermittancy in connections.

unsurprising: could help beyond your router, but shouldn’t help locally
:((( Deactivating ip v6 also…
a good move generally, but are you saying that it didn’t help?
where are you expecting to get names resolved (DNS)? Is that your router? do you have your router’s IP set up in ‘/etc/resolv.conf’ as the source of name resolutions?
Are you using, eg, network manager (or wicd)? Are you trying the connection before NM has chance to get information from the router? (or maybe you are using ifup/ifdown)?

Not in principle, but there are several ways of doing it in each system, so it is probably different in the way that you have it configured.
Could you try the command ‘ifconfig’ and post the response, please?
