MTU help

[UKSawkins]

I hope someone can help, Ive been reading the forums now for a few days and see a few people with the same problem as me, but cant quite fix it.

I have a lenova m58 with marvel onboard network card, and a intel 1000 i added.
This connects via pppoe to my broadband using a Draytek Vigor 110 as a pppoe - pppoa bridge.

Everything seems fine, but I seem to get packet loss on html pages on my clients.
If i ping the webpage the responses are fine.
It just sits at a white page and doesnt open the webpage.

My question is, how do i find the sweet MTU, as this seems to resolve it for most people.
Ive tried 1450 1400 1000 and keep getting the same results. Most pages are fine, just 30% of websites seem to just display a white page.

Any info would be greatly appriciated.

Steve

Do some ping tests. Set it to not fragment, then try with various size packets.
