Internet connectivity, i got a huawei e160 modem. ISP is one of the local mobile phone operators(safaricom). Am sure the modem is working fine coz it works perfectly well on other computers. Thats why i think a virus is causing this problem.
After loading the first webpage i always seem to lose internect connectivity forcing me to reconnect and load another single webpage!!.
Please help me with this. Your suggestions will be appreciated.
