I connect my laptop[dell inspiron, windows 7] to dlink dwm-156 stick and access internet by inserting sim into the stick.
It was working fine till last week.
from last week, the connection status shows connected, I get ip address to my laptop, and dns server ip addresses.
++even a default route is formed.
++I cannot ping ip addresses [including 126.96.36.199 and 188.8.131.52]
++signal strength is good
I forgot to mention that I have already tried multiple SIMs and all of them give the same result. So I suspect something might have have been changed on the pc. But I tried to track the event logs on the pc but did not find any.
Also I do not see any traffic being blocked by my MCAfee antivirus/firewall as well from its logs of blocked traffic.
++I do not see the traffic leaving the pc.[ because when I did traceroute to 184.108.40.206 I get all *** but no hops with an ip.
++I suspect that the data is not leaving the pc in the first place.[if there is any data leaving through my data card then it will log the in bytes and the out bytes--but no such logs are there in it]
Please suggest if there is anything I need to check on the pc.
I got a mail from mcAfee saying that they made a mistake and released a buggy update in their last release which made many users lose internet connectivity.
I will uninstall mcafee and check if it works.
I'm having the same problem. Went to the McAfee site and followed instructions to download tool kit and updates. it worked for about 30 minutes, but then the same thing happened again "Connected, but no internet access".
It always says "connected", but it fluctuates from "Internet Access" to "No internet Access" randomly. Even uninstalled and reinstalled McAfee as a 3rd suggested option by McAfee themselves. Still having problems.
Could it be something else? My other PC, phone and tablet all tun off the same wireless router and modem, but don't have any problems.
I can access internet through mobile using the same sim.
I have already contacted my ISP but they say that there are no issue with their network.
That indeed is correct because I am able access internet through mobile but not laptop.
