Welcome to Vodafone Community
Your speeds are very low, but without knowing how far you are from the cabinet it's difficult to comment.
However the upload SNR is very high so you should be able to get more upload speed.
What does the BT checker say your line should be capable of?
Unfortunately, because of the distance from the cabinet, you are never going to get much more.
Any chance of FTTP in your area?
Your SNR's show you could get a little more, especially on the upload. Have you tried with the router direct to the test socket?
You are getting a few CRC errors so DLM may have slowed your line to keep it stable
Sorry I couldn't suggest anything more, maybe someone else may have better ideas, but I think with the distance to the cabinet you are pretty much limited in options.
I accept its the distance from the cabinet. When I was on 7mb it was bearable but now at a sync of 5.2 its very poor at times. 7 down to 5.3 is around a %25 drop.
Can't blame Voda as it falls within their minimums but I do think something is amiss.
Just so frustrating.
There..... I feel better after that 🙂
I did try uos. I proved that 4g was not an alternative. Result was accepted for uos. They wanted around £30000!!!
Ps..I live in a built up area. Not in the sticks.
Just wish the line would have a serious fault so that it could be investigated.
I do wonder if changing to a new provider would introduce new lines / routing in the exchange..
Changing to a new supplier probably won't help much unless you go to one of the smaller ones (Zen, Andrews & Arnold, etc) who are better at chasing Openreach for work to be done.
Might be worth canvassing neighbours, contacting the community council, etc. If this is a local to your area problem there may be an opportunity for eg getting a new PCP cabinet closer to you.
