Hi,

I have a problem that is driving me mad!  I had an old router which connected 2 wired PCs to the Internet and it worked fine but had no wireless facility.  I recently purchased a Linksys WAG200G router.  The first wired PC works fine, the 2nd. wired PC will not work, but at this PC the network adapter seems fine: local area connection indicated as working.  A new 3rd PC works fine on wireless.  I have tried just about everything for the 2nd PC, moving it next to the router, using the same port on the router as the 1st PC, using the same cabling as the first PC. All the port lights at the router indicate okay.  I  also reset the IP setting on the 2nd. PC.  Gone through the router settings again and again, even tried wireless on the 2nd. PC: all to no avail!  (All the PCs are Dell, of different model nrs. but recent). 

Tried the Linksys community but with little help.

Would be extremely grateful for any suggestions!

Welcome to the forum, swissbill.

I'm not an expert on this subject, or anything else for that matter, but I once had similar problems with a Linksys gateway. Are all three PC's running XP or Vista? I couldn't get a PC running ME to work in my case, although it would work with Linux.

I'm sure somebody with more expertise than me will be along to help soon.

Hiya

I take it that you have switched everything off (so the router and all PCs are off), to give any weirdness chance to disappear?

What happens on the second PC if you go to a command prompt and type tracert www.bbc.co.uk (as per kitz's tutorial here)

If that doesn't work at all i.e. gives you "Unable to resolve target system name" then it's a problem with DNS on that PC. If you type tracert -d 195.62.28.175 (this is the address of kitz.co.uk) then it should work.

Whatever the results of these tracerts are if you would be good enough to copy and paste them in here as per kitz's Save Results page, then we might be able to see what's going on.

Presumably the router is configured as a DHCP server, and all the PCs are configured to get their IP addresses by DHCP?

[mr_chris]

You'd hope so... actually, swissbill could you also type ipconfig   /all into a command prompt on both the "broken" PC and one of the working ones, and let us know what that says too.

Hi Bill

Thanks for doing that - unfortunately it looks a bit weird to me! It's like your PC isn't recognising that you have a router connected - very odd..

Can you please type route print at the command prompt for me and let us know what it says? Also arp -a might give me another clue.

The theory I'm working on is either (a) your PC's routing table is foobar'd... but given you've said you reset your IP settings (presumably with netsh int ip reset?) that shouldn't be the case, but it's worthwhile having a look anyway...

or (b) you have some kind of what's called an LSP hijack... more info at http://www.kitz.co.uk/tech/TCPIP.htm - download and open LSPFix and if you could say what's in the list of "Keep" entries, and if there are any problems found, I can try and help diagnose if this is the case or not!

Cheers

[swissbill]

Hi Chris,

THanks for your help.  The reset I use is from Dell support : Reset the TCP/IP settings (XP): netsh int ip reset dellip.txt  I do not get any answer on this command, but Microsoft seem to indicate that this could be normal.

I noticed mr_chris was logged in earlier, swissbill. Reckon he's gone to scratch his head, or phone a friend about your little conundrum.

[swissbill]

Hi Chris,

In terms of plan (b), I downloaded Microsoft's guide to reset IP settings on the working PC and ran it on the "broken" PC - the program completed successfully, but the PC still did not connect. I then downloaded LSPfix and ran it on the "broken" PC - program Winsock2 Repair facility - and was flagged "No problems Found."  (I did not attempt the advanced settings.)

The PC seems to be working, but will not recognise the router.  I think that at this stage, I'll put back the original router and check whether the "broken" PC will still work with it! If it does, I'll rethink my options.

Thanks for all your help,

bill

[kitz]

I dont fully understand routing tables - so I'm possibly pointing out something stupid.

But why is the local link block 169.254.0.0 pointing towards a specific IP in that range for the gateway (169.254.154.212)?

If you follow that through 169.254.154.212 goes back to the loopback address.
Similar with multicast 224.0.0.0. points to that particular IP address.

If I look at my own routing table all gateways/Interfaces are in the same range [either "home" or the PC or router IP addy]

>> No ARP Entries Found



When I first saw your post I suspected either firewall or a DHCP problem.. the LSP thing was also something suspected - several years ago that used to be pretty common by certain malware, but not something I see as much mention of these days thankfully.

Have to wait see if chris can shine any light on the above...
I know he was in work today, but nipped home early afternoon to do something before having to go back there later so he may not have had chance to look properly yet.

[mr_chris]

Yes, certainly scratching my head over this - it works... yet it doesn't?

Routing table looks ok to me - I am wondering about the APIPA address though (169.254.x.x) why you have so many of those, plus a reference to network interface #2 - when in fact you haven't got one listed at the top of the routing table.

However, given there's only one default gateway, and it's pointing the right way, I can't think what's going on, although I suspect it may be something to do with that extra interface that's being reported.

As for how to go about sorting it without actually sitting there, I don't know.

I will continue scratching :|

[swissbill]

 

Well, the plot thickens or maybe it's me.  I had another look at the router settings.  My ISP (bluewin) seems to recommend PPPoE for encapsulation, the Linksys manual recommends RFC 1483 Bridged, while the guys at the shop insisted upon RFC 2516 PPPoE, which works in a limited sense as it gives me 1st PC wired, and the 3rd PC via wireless, but the 2nd PC wired is "broken".  After attempting various options I reverted back to the original RFC 2516 PPPoE and discovered that the "broken" PC was now running full Internet access!  This lasted a few minutes before falling out and providing a connection only to the ISP's home page, with no access to any of their pages.

On this basis I will re-contact Linksys.

Cheers,

swissbill

[soms]

Since the linksys is an ADSL router, you really want to set the connection type as PPPoA (PPP over Asynchronous Transfer Mode[?]) if available, as this is the type of connection ADSL uses. PPPoE is usually used on cable routers.

[swissbill]

 

Thanks, but no connections work on config PPPoA, only on PPPoE. Linksys recommended that I upgrade to the latest firmware for the router.  Which I did do, but no improvement, except for a disillusioning few seconds when the 2nd. PC connected to the Internet for a short time and then fell out once again .....
