I have a strange problem which has been going on for some weeks, even months.
After web browsing for a period of time, I can no longer access certain websites.
Things get unblocked if I either
1) reconnect the network cable from my computer
2) reconnect the cable into the phone master socket (takes a few minutes for modem/router to re-establish the connection)
I cannot understand why only some websites are affected, whereas other ones like Gmail behave perfectly ok.
