Anyone got any good 'humble pie' recipes?
Before I called Zen support I decided to do all the usual steps of connecting to test socket with a different microfilter and turning everything off and on etc. I also isolated my network by disconnecting all equipment (wired and wireless) except for the laptop connected directly to the main router via ethernet. Lo and behold I started to see 70/18Mbps (down/up) and it was very stable. So, piece by piece I built everything back up starting with the faceplate microfilter and then router wifi and then finally the upstairs feed which is an ethernet cable which connects to an 8 port HP switch which in turn feeds a couple of other routers and some other bits and bobs. Suddenly I'm getting poor speeds again, but only when connecting to ethernet upstairs or wifi from upstairs. Hmm...
After a bit of diagnostics including a temporary 15 meter cable from downstairs to upstairs I find it's the ethernet cable which is bad and when I took the faceplates off to check the connections I find it only has 2 pairs of conductors hooked up (orange, green) and looks like a telephony cable not a Cat 5/6 cable. In fact the cable only has 3 pairs of conductors in total so is definitely not suitable for gigabit ethernet! To make matters worse the cable was doing double duty with the 3rd pair of conductors feeding a telephone extension point. Not ideal!
Sure enough, when I checked my HP switch, the connection was only running at 100Mbps full duplex which in theory shouldn't restrict a 70Mbps VDSL connection but when combined with the fact it's not at least Cat 5 and has a pair of telephony wires running alongside then all bets are off I'd say!
So, looks like I'll be pulling a new Cat 6 cable through the walls tomorrow and hopefully that should sort out my issues. So, apologies to Zen for jumping to conclusions, and to Talk Talk Business for suggesting their back-haul was to blame!
