Router reconfigures PC's and they can no longer access the internet via hardwired connection to DSL Modem.
Hardware Information:
- Buffalo Wireless Router/access point, Model:
WZR-HP-G300NH-AP - DSL Modem: Generic (actually not sure of manufacture).
- Service Provider: TOT (Thailand)
- Laptop-1: Windows XP and Belkin PCMIA Network Card
- Laptop-2: Windows XP unknown network card & Wifi
- Laptop-3: Windows 7 unknown network card & Wifi
Outline of Problem/actions taken:
After a recent power failure the router and laptop-1 connected to router were no longer able to access the internet. Actions taken to try and recover internet access:
Using Laptop-1 tried to configure Router with PPPoe settings using software from Router Manufacture.
During the installation process a Timeout error was experienced, unable to connect to WAN.
Used Internet Explorer to communicate directly with Router using IP address.
Changed settings to use PPPoe settings given by ISP.
Router was not able to communicate with Internet.
Repeated steps 1-4 again with no success.
Reset Router and DSL modem.
Repeated steps 1-4 again still no success.
Tried connecting Laptop-1 directly to DSL to gain access to internet to research problem.
No Network connection with DSL could be established…connection would be established for a second and then be lost and didn’t appear long enough to actually connect to DSL.
Replugged LAN back into Router and connection was regained with laptop-1.
Replugged Laptop-1 directly into DSL and again unable to establish network connection.
Uninstalled network card and all of its drivers on Laptop-1.
Reinstalled network card and drivers and tried connecting directly to DSL.
Still unable to make network connection.
Plugged DSL into Laptop-3 and Internet connection was established.
Being Laptop-3 does not have a CD-Rom, Laptop-2 was tried to connect to the router.
With Laptop-2 steps 1-7 ended up being repeated without success.
Tried plugging Laptop-2 directly into DSL and again no network connection could be established.
Using Laptop-3 with a direct connection to DSL downloaded latest Router FW.
Installed router FW using Laptop-1.
Tired the installation process again without success.
Being desperate reinstalled OS on Laptop-1 still not success.
Tried using “ipconfig” with router to see what was going on without success.
With laptop-1 connected to DSL went through the “
ipconfig /…” inputs to see if anything made a difference. Being the network card was not able to make a connection this provide very little information “media disconnected”. So now I have a router and two laptops which are unable to connect to the internet and sure could use some advice/help.
