Afternoon all,

I've just seen a post in the newsgroups from someone on LLU claiming that they can't get to adobe.com or adobe.co.uk. Seems OK for IPStream customers though. as we've only recently changed the access rack for LLU customers I'd be appreciative if someone else on LLU can give this a whirl to douse my concerns. Peter, you around?

Rgds,

Rgds,

I've had issues connecting to it too... It works, just slow.

When I first went onto LLU I had a similiar problem with adobe and certain other websites - microsoft.com odeon.co.uk qxl.com

I was eventually advised (not by plusnet) to increase the MTU on my Netgear DG632 from the default 1458 to 1500. This solved the problem, and was repeatable. The explanation I was given was that these sites, amongst others, sometimes dispatch the data packets in chunks of 1500 at a time irrespective of the requested packet size (the MTU value of the modem). I think the story is a bit more complicated because each router the packet passes through has its own MTU, and the requested packet size should be the minimum MTU of all the routers.

However the occurance of this issue with the switch to LLU was probably co-incidental, because I was forced to flash the router with the latest firmware to establish a stable connection with LLU; and it was almost certainly the new firmware which was handling the MTU setting slightly differently.

And finally plusnets response to my findings "we do not advise changing the default MTU setting on your modem". Well it was during the pn meltdown phase last year.

Hi,

The MTU thing is interesting, I've seen a lot of similar cases. Generally the sites that are affected seem to be Microsoft as you saw (including MSN and Hotmail), amazon, ebay and the London Congestion charge site. Never found a definitive pattern to it, but in most, but not all cases it seems at some point each person affected by this has done some tweaking of their connection. Then when they've either changed ISP or changed speed or even changed network the tweaking needs re-doing.
