I also tried: rebooting the notebook, restarting rvice, rvice, reconnecting via GUI, disconnecting my Ethernet->usb dongle and connecting it back with service restart but to no avail. The only thing that helps is rebooting my router, which is really weird.

Also I checked ping and it reported 0-5% package loss without almost any 'time' changes. I also performed a speed test (ookla) and the results were 4 times less than my normal speed (it was 16Mb to local provider when my normal rate is 100Mb) and even so, when I monitor my connection through iftop it's usually like 200kb after resume. So basically my problem is the following: after I suspend my notebook and resume my internet gets really laggy, for example sites take much longer to load or fail to load, cannot properly buffer video, etc.
