I have an ongoing problem with my Zen broadband connection (connection drops, hobbled upload speed), which coincides with intermittent noise during phone calls (BT landline account). Both of these faults appeared at the same time.
A replacement Fritzbox router was a bit more stable but the basic issue persists.
BT sent a nice Openreach engineer last week who spent 4 hours troubleshooting the phone line and appeared to make an effort. Over the weekend the noise (and internet connection drops) resumed.
The connection drops coincide with noise on the landline. Download rates reported by the Fritzbox router are barely affected, while uploads are badly hobbled.
Worst example : 65mbps / 0.4mbps. Usual rates recently have been 70/13. In January they were 70/18 but then suddenly worsened.
I've attached a screenshot of the Fritzbox's 'spectrum' info.
Does anyone know of a reason why a frayed aluminium cable or other landline fault would so selectively affect upload frequencies but not download ? Can a faulty DSLAM be causing noise (crackles etc.) during phone calls ?
Today is a bank holiday so will have to contact my ISP tomorrow, but would appreciate input from someone who knows more about these things than I do.
Thanks in advance.
