I've been having problems with my infinity for roughly the last 2-3 weeks where the speed slows down to a crawl in the late afternoon and evenings. During the day, I get the 65-75Mbps that I pay for but every day, without fail starting between 5 and 7pm the speeds start dropping untill they reach somewhere between 2-15Mbps. These numbers come from the BT wholesale speedtest and were done with only one wired device connected to the router.
I've spoken to BT about this twice now, the end of the first conversation left me waiting 3 days for them to call back this monday while I "monitored" the connection. As expected, nothing had changed. When BT called me back on monday, it was in the morning, so naturally my speed was fine. The representative I spoke to didn't, until pressed, seem interested in doing anything else and wanted me to wait another 3 days before calling back because "it all looked fine"! Once pressed, he ran a test on my telephone line and told me there was a fault. I was told that my case had to be sent to "level 2" customer service or something of the sort and that they would ring me back on wednesday between 1-3pm. I had to take time off university to be able to make that slot, all others this week clashed with my timetable too badly. It's now 4pm and I've yet to recieve a call.
Honestly, I'm fuming. I don't know what the issue is, but I'd imagine it's got something to do with congestion on the line, since there is only a problem in the evening. I'm paying full price this month for a service that hasn't been delivered in my opinion. I guess I'm going to have to phone support back this evening but I've pretty much given up all hope that they'll actually do anything. I'm sick of having to repeat the same steps for 45 minutes every time I speak to someone, I mean seriously, it's like they don't keep any records! I'm hoping the people on here are a bit more helpful/competent.
Here are my results from the 3rd test on the BT wholesale speedtest, as you can see my IP profile seems to be correct. I have restarted my router once on friday, as per the instructions of the customer service rep I spoke to, but no more than that as I know that can actually cause an issue that reduces your speeds.
