Not sure if anyone can help, I had FTTC installed just 2 days before I went away for 10 days. When the BTO engineer fitted the service, he could test the telphone but was unable to do any speed test using his equipment. And I was unable to test via the bt speedtester site.
Now I am back, I have noticed that my speeds drop from around 55/17 on a day time to around 30/8 on an night and I am still unable to do any test using BT speedtest site.It performs the test but when it comes to displaying the results it says error. I have tried different machines and using a wired connection. I have connected an alternative router to the openreach modem but the speeds still drop on a night and unable to do a test and see my profile..
anyone got any ideas, comments or suggestions? I am not sure if the speed drop is congestion or if I have a problem with it not allowing me to test my line?
