Are upstream power levels typically this low on Vodafone Fibre 2? Currently getting -7.6 dBm
I swapped from BT about two months ago and have noticed a big difference when playing games on my new Vodafone connection. I play a clientside game, where hits and kills are registered on an individuals computer and then sent to the game server for registering. They are then checked and cross referenced with the oponents data. If there is lag in sending your data then it can appears as a kill lag on screen. I have noticed hits coming through instantaneously, one big instantaneous mag dumb followed by a kill, and none of my hits getting registered.
I think I may have an upload issue with my Vodafone connection. I live right next to the local exchange. It's my next door neighbour. Street cabinet in right outside my house. Line is likely very short, hence all the other good line stats. But the upload looks horrible. Errors and low power levels.
Modem is connected directly to the test socket. No filters needed as no phones or fax machines in the house. No other internal wiring that could be at fault as I'm connected to the test socket. There's some interleaving on the download side for some reason, but no delay has yet been added.
How does the upload side look to you guys?

On a logarithmic scale, -7.6 dBm represents a power level of 0.174 mW which is only 17.4% the value of the target power level of 1 mW. That's 82.6% weaker than it should be.

@Bvertly I was too lazy to do the maths and just had a magnitude table on a card. I can even use a slide rule 😂😂
