All 3 of my 2860's don't have the Hardware Acceleration menu/option so can't disable if it is enabled

I have recently upgraded to 3.8.4.3_BT. Skype connections are still intermittent. Internal Contacts keep popping up online even though they have not signed in/out. I have had a look and hardware acceleration mode is set to Disabled.

This appears to have started since upgrading to 3.8.4.3. Was fine before. No other router changes have happened.

As reported on another thread, 3.8.4.3_BT works fine for me, stable vdsl (Zen over BT backbone) and WAN2 wifi connections, WOL now works as well.

3.8.4.4 BT has been released which looks to have resolved the hardware acceleration issue from the release notes.

3.8.4.3BT has been very stable with regard to VDSL uptime so hope this continues.

I have tried both 3.8.4.4_VT3 and 3.8.4.4 BT firmware and still I get Skype contacts on/off constantly even though we are in same office on same WAN connection, delays in sending messages, delays in calls being answered.

I dont think the internet is dropping, just appears to be skype.

Does anyone have any ideas?

I had all sorts of problems with 3.8.4.4_BT line disconnects. Connection would be stable for days and then I'd get numerous disconnects in a short period - so much so DLM was applied to my line.
After some trial and error with the other versions, I switched to 3.8.4.4_VT1 which has proved to be rock solid for the last 5 weeks.
