My TV suffers the most as I typically watch Netflix, YouTube and Amazon video, where all services have periods of buffering. On my PC I notice issues as, intermittently, websites will hang whilst loading; an example is Gmail whereby it hangs for up to 1 minute on the splash/loading page prior to opening my inbox.
At this point I am trying to rule out any potential issues with the RB4011, before contacting my ISP to have them investigate from their end. So far I have tried
- Reset router to default/factory settings to rule out any customization errors, of which there was one (ip address was assigned to ether2 instead of bridge, can't recall doing this but I'm sure I misclicked at some point)
- Added Firewall Mangle rule for change-mss to clamp-to-pmtu
- Added Queueing rule to prioritise ACK packets.
- Put my ISP modem back into router mode and hooked directly into that to reproduce the issue, but it's tough to say if this actually worked because the issue happens intermittently.
