There are multiple posts on the slow speed on this router but I did not find any that are similar to the issue I have. I have also tried most things listed apart from a factory reset as avoiding till now the need to set everything back up.I recently upgraded my internet connection from 200Mbps to 500Mbps but noticed I was not getting mush of an increase. Doing a speed test on the router shows a good speed but a speed test from PC is around 250Mbps. I have QAS disabled, Traffic Manager disabled, on latest firmware and have re-applied the firmware, I do have access controlled enabled though.I did one more test today and got some weird results.If I enable QAS my speed dropped from the normal 250Mbps to about 160Mbps. When I then disabled QAS the speed test went to 395Mbps. This is speed test from my PC, yet during that time I did a speed test on the router and got 517Mbps. I have also noticed the speed test is gradually getting slower from my PC. 1 hour later and the speed test has dropped to 334Mbps, with router showing 508Mbps on a speed test there. Once again, I enabled QAS and disabled and the speed test from PC went up to 380Mbps. Still 120 Mbps from what the router speed test gets but better than the 50% I am normally getting.Sorry for the slightly long ramble on this but wanted to give plenty of detail. If anyone has had the same issue and a way to resolve it. I would appreciate any information you could provide that could lead to a possible fix. The router is 5 years old so getting on but if a fix is out there then no need to replace what has been a good router up to now.Cheers.

HIFirmware Version - V1.0.4.62_10.1.74Modem is Virgin Media Modem working in Modem only mode. Of the 4 services only 1 enabled is access control. I will do a backup, try the disabel access control and see how that goes. After that, then looks like factory reset and see how it is before re -setting things up. To be honest may be best option as it has been sat running for 5 years and never had a factory reset, a reboot every now and then and firmware updates as needed. Thanks for quick response :)

What firmware are you on? What modem/gateway is it connected to?there's 4 services we usually recommend disabling to get full speeds: access control, traffic monitoring, parental controls, and qos. If you've had them enabled, try the factory reset and clean install (not from backup). This can usually help. You can always try disabling the services and rebooting and seeing how it works. Or even disable them, do a backup, factory reset and then install from backup. worst case, it doesn't help and you need to just do a clean install.

Slightly baffled as I was expecting to need to do more but here is what I did. Made no changes and did a speed test to get a baseline was 302Mbps on router it was 507Mbps.Did a Backup of Router configDisabled Acces ControlAnother speed test and was now 329Mbps. Rebooted router and ModemAnother speed test and this time shows as 553Mbps but speed test on router shows 358Mbps. Essentially all I did was a backup, disable access control and a restart of modem and router. Speed jumped by 250Mbps. Did another speed test to see if it was a one off and got 523Mbps. Going to leave as is and see how things go for a few days then may re-enable access control and see what impact it has.

the speedtest on the router isn't reliable (through the app). Reason why is it usually picks the closest server and not the fastest server. Its nice to have but if you have reasonably fast internet, its not reliable because you can't change servers.
