Connection issues

[#1]

I have a TG589vn v3 router and it seems to be dropping connection every so often. Also my Xbox seems to be lagging significantly recently on most games. VPN to work is a bit laggy too.
Can someone check my line stats? This is what the router is telling me:
2.1 Type VDSL
2.2 Status Up
2.2 Uptime 0 days 0 hours 14 mins 35 secs
2.3 Line Rate (Down / Up) 47161 Kbps / 18708 Kbps
2.4 Noise Margin (Down / Up) 6.3 dB / 6.1 dB
2.5 Attenuation (Down / Up) 11.1 dB / 0.7 dB
2.6 Power (Down / Up) 12.9 dBm / 6.8 dBm
Thanks

Hi dcbuckley,
Sorry to hear about the problems you've mentioned.
After checking your account details and running some diagnostic checks I can't see any obvious problems.
As the next step I'd try connecting up via ethernet temporarily to see if the connection still drops. If not you may need to look at making a few changes to optimise WiFi performance:
