Connection only half working

Hi !

I'm having troubles with my internet connections for about one month : only about half of the requests I send on the network are answered by the remote server. For example, if I want to display a web page, I must refresh it about 10 times before having it completely loaded.

I'm connected on a shared network, and I'm the only one who has this kind of problems with the shared connection. I tried to disable the IPv6 module to see if it was the source of the problem, but it's still occurring.

Has someone here already had this kind of problems, and how did he solved it ?

How is your network shared? By a dsl modem or what?

Can you ping everything normally?

I can't ping anything outside of the network, it seems the router is blocking icmp...

The router is doing load balancing with the connections, redirecting them to one of the four internet connections it is linked to. I don't have more informations about the network, but I can say it works correctly as I don't have this kind of problems with Microsoft Windows.

Oh. It might be a MTU size issue, but you'd need to use ping to determine optimal MTU size.

You can still try use following: ifconfig eth0 mtu 1400 (or lower number like 1200).

With 1200, it seems I'm getting fewer connection problems, but they still occur sometimes. Even with lower values like 900 or 800 I'm still getting some errors. Anyway, it's much better like that, thanks .

Thats weird. Could be buggy NIC driver or router doing some weird stuff.
