I am having this problem for the last few weeks. The modem will remain connected, the DSL/Internet/LAN lights will be all turned ON but the Internet will not work, it will tell me that there's a connection problem so I cannot browse or do anything. This happens sometimes, at intervals, sometimes the day will pass and this will not happen, at other times, it will happen several times within 10-20 minutes and gets fixed by itself within a minute or two, sometimes more.
Is anyone else facing this problem?
P.S. When this happens, I am not able to login to the modem settings as well. Could it be that the modem OR switch is faulty?
