I bought a new modem a few weeks ago (D-Link DSL-2730B) and about a week later it began to drop the connection randomly and would then connect to an unsecure network called RT3052_AP.
so why is my modem changing it's name?
Could it be a virus?
YES. To be sure it is not and can not be in the future do this:
a) find the latest firmware for the D-Link DSL-2730B and download it.
b) disconnect from the modem to go off-line
c) use a wired connection to the router and while connected,
use a paper-clip to press and hold for 5sec the rest switch on the back - - the router will reboot
d) use your browser to access the router conf page
e) reload the firmware from the above download (router will reboot again)
This ensures some virus, if present, has be eliminated
f) Disable Remote Management from port 8080 and
now go to the router security page and set a new admin password.
This ensures you can't get hacked again.
g) now setup the WiFi and change the SSID and use WPA or WPA encryption to
keep your router private.
There's a very
negative review here which indites the MTU setting change and for ADSL, you really need 1492.
It takes a regedit to fix it however
