Router problem
Sorry to bother you all with this, but this one has got me stumped! The other day I set up broadband and a Netgear MB814v2 and straight out of the box it worked first time. The next day I had to shift computers back to different rooms and I changed monitors on the m/c that's connected to the cable modem. That's where the problem started, there was a conflict with the driver and Windoze wouldn't shut down properly. After a bit of fiddling around including reformatting and installing a fresh copy of 98se I realised it was the monitor and changed them around again. However this is now the scenario; There are three computers A, B and C all running 98se, A is connected to the router and the cable modem. When I fire everything up B and C can see each other over the wireless LAN but not A and A can see nothing. Funny enough when I open a browser on B or C I do get the Netgear home page wizard but that's all. A can't ping the router nor any of my isp's servers, B and C can ping the router but not the other servers. I'm pretty sure it's not hardware, I've reset the routers to default, changed NIC cards and cables, reloaded protocols and TCP IP. I'm missing something fairly simple here, any ideas gratefully accepted. Best regards Tony On Sun, 06 Mar 2005 02:31:37 +0000, in alt.internet.wireless , Tony Yarwood

Then do ipconfig on each machine, to ensure they correctly got an address. Anything with a 169.etc address is bad. If you still have one mch with a bad IP, then try swapping network cables round, and try using different ports on the router. Given that you've moved kit around, its quite possible that a cable got kinked or a port died on the router. -- Mark McIntyre CLC FAQ <http://www.eskimo.com/~scs/C-faq/top.html> CLC readme: <http://www.ungerhu.com/jxh/clc.welcome.txt> On Sun, 06 Mar 2005 13:00:47 +0000, in alt.internet.wireless , Mark

Is computer A in a position with poor wireless reception? -- Mark McIntyre CLC FAQ <http://www.eskimo.com/~scs/C-faq/top.html> CLC readme: <http://www.ungerhu.com/jxh/clc.welcome.txt> On Sun, 06 Mar 2005 02:31:37 +0000, Tony Yarwood

When you reinastalled "A", did you do it by cloning one of the other computahs? If so, you probably also cloned all the settings including the wireless MAC address in the registry. Duplicated MAC addresses on a LAN is not a great idea. >When I fire everything up B and C can see each other over the wireless Duz "A" have a valid IP address?

Too many possible reasons to list. Try turning off encryption for now in the router and see if it connects. >Funny enough when I open a I take it that means you can communicate with the router from "B" and>browser on B or C I do get the Netgear home page wizard but that's >all. "C". Go to the "status" page in the router and see if your unspecified WAN connection is functional. You should see real routeable IP addresses assigned by the ISP. If not, you have either an ISP, modem, or router setting problem. >A can't ping the router nor any of my isp's servers, B and C can ping What other servers?>the router but not the other servers. >I'm pretty sure it's not hardware, I've reset the routers to default, Sigh. This would be a great time to start from scratch.>changed NIC cards and cables, reloaded protocols and TCP IP. Take either "B" or "C" computah and plug it directly into the router using a wired LAN CAT5 cable. If they're too far away, drag them over to the wireless, or find a long CAT5 cable. You'll find it easier to do this if you have everything in one room during troubleshooting. Disable the wireless in either the router or the clients. Turn OFF the other computers. One modem, one router, one computah. Now, get yourself a working ISP connection to the internet. When you get that functional, plug in "B" or "C" and get it working. Again, no wireless. After that, get "A" working. Turn OFF "B" and "C". One machine at a time. Here you may have a problem because you've either screwed up the Windoze 98SE reinstall, or misconfigured the TCP/IP stack. I don't have enough info to figure it out. Now turn on and plug in two machines at a time. See if it works, again wired LAN only. If so, now you can turn on *ONE* of the wireless radios, setup encrytion, and do some testing. I think you can probably see the methodology and fill in the rest yourself. >I'm missing something fairly simple here, any ideas gratefully The idea is to NOT troubleshoot everything at one time. >accepted. As for machine to machine communications, try ping first. Then try: Start -> Run -> \\machine_name or \\machine_IP_address and you should get a directory without waiting for the "master browser election" nonsense. -- Jeff Liebermann je***@comix.santa-cruz.ca.us 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 AE6KS 831-336-2558 On Sun, 06 Mar 2005 10:37:23 -0800, Jeff Liebermann

How? Via wireless or wired? router and the cable modem, or the more likely culprit the interface, Windoze. When I connect A, B and C through a wired hub everything's fine, they all see each other and A cam ping the net. On computer A there are two LAN cards eth1 is set to automatic and is connected to the cable modem, eth2 is connected to the LAN. On the LAN side of things I prefer to have fixed ip's (makes it so much easier to ping etc.) Eth2 is set to 192.168.0.2 and the gateway is 192.168.0.1 (which according to the Netgear manual is the router default). B and C are set at 192.168.0.3+++ with the same default gateway. When I put the wireless router on, the only thing that works is the wireless connection between B and C. Computer A can neither ping B,C or the net. Nor can B ping A, it can ping the router tho. It totally screws up the cable connection, I can't access the web at all. It also doesn't work when I hardwire B or C to the wireless router. I'm beginning to think I've screwed up the router; I find out now that they're quite sensitive souls, I left this one on top of the CRT monitor for a while the other day, duh. > No, I don't think so, I reformatted c:\ and clean installed 98se .>When you reinastalled "A", did you do it by cloning one of the other >computahs?

Thanks Jeff, I do try to be methodical and try just one fix at a time.> Many thanks for your trouble in replying. Best regards Tony On Mon, 07 Mar 2005 12:50:50 GMT, Carmen <Carmen.Br***@clara.co.uk>
