slow speeds even with hardware change

Hi All,

I just setup a Point to Point Wireless link between my place and a mate a street away (approx 150m line of site)

we have done testing with the wireless link between the houses and max out about 60-70mbit both ways.

so I was happy with that as I ordered a 100/40mbit link

Problem is the sophos seems to have an issue with anything over 40mbit... i can get 40/40 pretty much all the time (I have even changed hardware from an atom to an i7 as I thought that was the issue)

but as soon as I plug my lappy into Point2Point link and establish a PPPoE session I get 70/40 without sneezing.

I have tried a restore sophos, I have tried a fresh install without any extra features enabled, checked QoS, I have even tried another brand of NICs (Realtek/ Intel) and always I hit a bottleneck of 40/40....

another thing I tried was setting the auto-negotiation down to 100mb full duplex which sees the speed drop to 10/30 which is weird in itself

I am also testing from a cable plugged straight into the UTM (so nothing else on the network, and wifi disabled.)

any help would be appreciated.

Regards,
Aza

  • Interesting.  Is there anything interesting in the IPS log - maybe some Anti-UDP Flooding activity?
