Knackered Router?
17 Answers
I can't get my laptop to connect to my router. All has been fine for a couple of years, but now all I get is 'limited connectivity' and it looks like it won't give me a proper IP address.
I've tried wireless, ethernet and USB, rebooted, restarted and done a factory reset on the router but still the same story. I can see the router but only get limited connection.
Any ideas or shall i just buy a new one?

you don't say which flavour of windows ... so we'll stay general
two methods of connecting to router ... wire and wireless
the most reliable is wire ... so you need to use an ethernet cable
first restart your lappy and router .... count to 50 then fire router ... when router is started (90 seconds?) fire up lappy
connect with the wire
give it 30 seconds
then try it with IE
if no joy
type the following in a command prompt
ipconfig /all
ipconfig /flushdns
ipconfig /release
ipconfig /renew
this will show your ip addresses
(the gateway should be the router ... so you need 192.168. ... or something in there)
in your case it looks as if it sould be
192.168.1.x (x= a number between 2 and 252)
if you get a 169 address part of your router isn't talking to lappy (dhcp)
so let's start testing
type the following - press enter at the end of the line
ping 127.0.0.1
you'll see something like this

Have read and digested that now. So your thinking is to check that the network adapter works correctly first, and rule that out as the problem,right?
There were 3 items in network connections (I'm on XP by the way). Wireless adapter, LAN adapter and something else I can't remember (1306 rings a bell?).
Am I right in thinking that these are all distinct items and one of them breaking shouldn't affect the others? To me, that would then point to the router itself being the problem. It just seems odd that I can't get at the router either wired or wireless.
If network adapters are not OK, then what? Try re-installing drivers?
And if they are OK, try a new router? I've bought a new one just in case but I can always take it back if I don't break the seal.
Sorry for all the questions but I want to try to get this sorted tonight one way or another. My knowledge of PCs is reasonable so I'd like to think I can get this sorted with a few pointers in the right direction
Thanks again.

The 1306 thing in your network connections will be your firewire card. For some stupid reason, Windows bundles this with the networking stuff (it can be used for networking, but usually isn't).
Not to jump in on AC's answer, but I would suggest doing the following:
1) Turn off all stuff. Then turn on router, followed by your machine (ideally connected with a cable, not wifi), in that order, and waiting for a few minutes between.
2) Goto the command prompt (on XP it's start->run, type "cmd", then in the black window that appears type "ipconfig /all". (no quotes).
What information does it give? (copy all of it to here.)
What is the brand and model of router?
When you connect router to PC via ethernet cable, do lights turn on and/or flash on the back of router and/or your PC?

It's a Belkin 54G if I remember rightly.
I�ve tried all the turning all the stuff on and off numerous times but will turn them on in that specific order just in case that does it!
When connected via cable, lights do flash on the lappy and the light on the router does come on to say something is connected. It kind of connects, but I always get 'limited or no connectivity'.
I'll do the ipconfig thing and post back when I get a chance.

you sound to have your head round it
it's quite simple .... break down every stage ... into hardware/software
and work through.
so if lappy OK ... could be - could be
each step has (in effect) an ip address - or at least one that tells you something
127 only works on the lappy if the drivers are installed .... and there is s network device
(or at least what looks like one - it's a bodge test ... but it works a lot of the time))
you will only get a 169 address if windows sees dchp is missing ... and the network card can see what looks like a hub or switch port
if dns is missing ... you can ping an IP address ... but not a domain name
not as good as an electrical test ... but it will only take 5 mins to work through it
fo3 often put's things in a less wordy way that I do ;-)

Right. I'm online with an ubuntu live cd so the router obviously does work, just Windows that doesn't.

Yes, same machine with ubuntu. You could be onto something with the firewall � I updated ZA a week or so ago, though it has been OK since then, just suddenly lost connection in the middle of a net session.
I�ll try removing and updating the drivers tonight otherwise I might have to resort to restoring a backup image of my hard drive. Haven�t backed up for a few months though so would rather avoid it if I can.

woa there bigboy
which version of zone alarm?
and vista or XP?
there was a panic a few months ago when an update killed all network
just found it again!! - see if this sounds familiar
(if not it's still a fair bet it's the firewall)

*sigh*
I don't think it's the firewall. The fix AC linked to didn't work cos I couldn't remove the windows update it mentioned. I can see the update, but it says it can't be removed.
So I uninstalled ZA completely. And disabled windows firewall. And removed all network adapters. And re-installed them all with the latest Dell drivers. And rebooted. Again. And did a little dance just in case.
But I'm still getting the same 'limited or no connection' via ethernet and wireless to the router.
Have I got you both beaten yet? I think tomorrow evening I'll bite the bullet and restore my hard drive image.

This might be relevant....
I'm looking around the router settings (using ubuntu obviously) and the router's firewall log has a few warnings popping up at around the times I've been trying to connect with windows.
Quite a few of them say "Blocked - NAT out failed First packet in connection is not a SYN packet: TCP 192.168.2.2:38822->88.221.205.68:443 on ppp0"
and one or two say "Blocked - NAT out failed Packet not in tcp window: TCP 192.168.2.2:44419->74.125.4.28:80 on ppp0 [repeated 3 times, last time on Apr 2 19:22:28 2009]"
