Poor connection quality with slow data transfer
Poor connection quality with slow data transfer
More precisely, the connection comes through the phone line. True fiber broadband isn’t available and most users in the UK rely on VDSL or fiber to the cabinet included in their plan. Was the speed at 5GHz? Do you have a WiFi analyzer on your device to verify the channel it’s using? Even at 5GHz, many people end up on channel 36, which can lead to interference from neighbors’ networks. You definitely need to check with a wired connection—your ISP would advise this. WiFi isn’t a dependable method for confirming broadband performance, as congestion issues are far more common than connectivity problems.
We’ve paid for a 74mbps down and 20mbps up plan, but 4mbps downloads still seem too slow. My wired test showed similar results—about 20ms latency, 30ms jitter, 11mbps down, 7mbps up. The phone I used runs at 5ghz on channel 36 and 2.4ghz on channel 1, which has been consistent for as long as we’ve had internet.
After restarting the router, ensuring the cables are secure, testing with an Ethernet cable, and still facing issues, it seems the only solution is to contact the ISP.
It's generally around 74Mbit, yet your argument remains valid that 4Mbit is poor. They usually won't offer the 74Mbit plan unless they believe you'll exceed 40Mbit, which suggests a potential issue. There seems to be a problem with the line, particularly with jitter—though you mention 30ms pings to the router, which shouldn't occur. Does this happen over a wired connection? Also, does the phone function properly? A sudden drop to single digits often results from a broken phone cable leg, stopping service but allowing VDSL to work very slowly.
