Flashed my 8800AXL today and to my surprise lost nearly 3 mbs of speed !!
It went 68.86 down to 66.1mbs not what I wanted to see.
Nothing else had changed and my line is a very stable connection on New cab installed 3 weeks ago and I am the only one one it.
In fact I am the only one on 5 miles of new BT back bone to main exchange, so not problems with congestion!.
Put Home hub 5 back on and went back to 68.8mbs
Factory reset router and made no difference and reflashed.
So will give it a day if not will have to go back to old firmware, bit disappointed that its going down and not up or even staying the same.
