Router Issues... again

DNS server correct - yes. I manually configured the router to point to the primary DNS server as according to the ISP's website.

IP addresses are all fine and dandy. My computer and router have nice lovely chats to each other except when the computer asks to speak to the outside world. My computer is like a subjugated wife.

A solution would be to put your computer's IP in the router's DMZ (after activating it). But this will rob you of any protection a router provides.

Perhaps if you could give the type of the destination unreachable message someone can help with a vague idea.

ICMP: Packet Type = Destination Unreachable
ICMP: Unreachable Code = 0x0D <------------- this hex number is of interest

(and: no, I'm not he who knows which type is generated if the network address resolution fails...)

A suggestion: is your router set to router specific mode. In my router, there is an option for router or gateway. Gateway allows your computer(s) to access the internet, and this mode will also perform network routing. However, if it is set to router, it will not connect to the internet at all (from your clients) although the connection may still be there. So check that on your settings screen.

To clarify what I am talking about:

Click, and it will open in a new window in full size /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Hope this helps

The world's slowest computer fixer is back!!! I finally got round to trying out these suggestions and discovered...

My router is mental /blink.gif" style="vertical-align:middle" emoid=":o" border="0" alt="blink.gif" />

Now... my router can't ping the internet.... BUT MY PC CAN!!! Where's the sense in that?! However I still can't visit webpages in my browser, I get the normal error. I can only ping ip addresses, otherwise I get "unknown host" errors.

An interesting thing I've noted this time, when i run ipconfig, as well as giving subnet mask 255.255.255.0, my ip address and the router's ip address as the gateway, it also has "connection-specific DNS suffix" - but this space is blank. Sounds like this is the problem (at the moment anyway?)

Other idea - would setting my PC's gateway to the actual gateway (ie what the router connects to as its gateway which I can see in the router log) help??

Regarding your specific advice....
heywood - I just get "unknown host" errors, nothing as specific as a hex code I'm afraid.
adam - my router doesn't appear to have any such differentiation.
Immz - thanks for the idea but I might as well just use the rubbish USB modem I'm using now, unles... that could be set up for 2 computers? I couldn't see DMZ anywhere without looking too hard, thought I would post the latest state of play first!

My router (or possibly my network card) has a little quirk in that my computer can't automatically pick up the DNS server address. Maybe yours does too. Go into your router status page, it should have one or two DNS servers listed. Enter those into your network configuration in your computer's control panel and see if it helps.

On my mother's computer the DNS client service was set to manual for an unknown reason. Maybe your computer made a similar mess?

Gandalf, catch me on IRC sometime. I'll try to do a remote login to your router and see WTF is happening in there. (Your router should support remote management - almost every router out there does).

Grimm's suggestion entails checking the services listing in Control Panel -> Administrative Tools BTW.
