I have a strange and terrible problem with my wireless modem router. It's a TP-LINK 8901G.
It's about 1 month that I have different time when I ping my modem (192.168.1.1).
When reply time is 1ms or about it, everything is ok. But after some time, time becomes about 50ms and I lose my connection to modem.
All modem lights are working and I have wireless signal but I have not any connection with modem. Even I tried connecting using cable, but the same problem I occur.
What do you think about my problem ?
