Home network & internet sharing problems
tagrant7 Jul-20-02 01:59 AM
Well... I have a desktop and a laptop that I have networked with a hub. I am running windows 98se on both. I can view each computer fine in network neigborhood. My file & printer sharing is working fine. I am on COX cable access and using a Motorola surfboard modem. My desktop is my main computer with the laptop in another room. The hub is a netgear 4 port hub. I do have 2 ip addresses from cox. But....... I can not get both computers on the internet at the same time. I used to be able to, but can not for some reason for a few months and can not figure it out. COX will not help but only with the computer that makes a direct connection. They will not help you troubleshoot a home network. "Against thier policy". I have tried the "release & renew" methods of winipcfg and that never works. It always has a windows default IP address of 169.????? I am sure my answer must be something simple... but it eludes this networking degenerate here LOL. Any help would be so very much appreciated. I don't know how i found this forum, but you can bet i am going to spread the news of its existence!! The reading has already been invaluable to me. My first visit..... I am excited to find it. Dang.... I hope I don't make a nuisance of myself! I am sure going router would be a better way... but can not do that at this time. Besides... I got a lot of sweat and tears invested in running all this cable in my attic! LOL I would like to make use of what I have... if I can. If I can't, then I might have to try to do something else. But... I used to have them both on at the same time... why not now? Thanks again for listening to me ramble and giving what help you can... much appreciated.

IP address of 169.????? means it isn't getting an IP address from cox or anywhere. See What are private IP addresses? at http://duxcw.com/faq/network/privip.htm. I don't think your MODEM is configuered to provide two IP addresses. If it is you should be able to determine that from the MODEM's browser menu that you should be able to access from the PC that is getting an IP address. I would forget that second IP, stop paying for it, if you are, and get a router (http://duxcw.com/faq/ics/waysshare.htm). Larry

First bet, Bad NIC. Try running a line direct from the modem to the PC that is getting the 169 IP. If it still gets 169 (after shutting down the PC and resetting the modem) Swap out the nics. If it's physically impossible to run the direct line, try the "Bad" nic in the PC that works.

2nd the opinion to get a router, It pays for its self and really cuts out ALOT of the problems that we see here regularly.

Sorry Matt... forgot to mention... one is desktop one is laptop. If it is a bad nic then it is the laptop cause i have switched it every way i could figure to do it. LOL I am on the desktop now. I can get on net with the laptop... but only through direct usb connection to modem... if i try the nic... it flashes the little light like it is trying to do something... but has one light that is steady and red. Red usually doesnt mean anything good... right? I am so happy to find a place where i can get someone to talk to me about what i am trying to learn to do! Thanks again everyone!

Tim

Thank you Matt and Larry!!!

I definitely am leaning toward the router way. I hate to show how ignorant i am LOL. I considered wireless since i am in a small brick house and the rooms are really close together, but then i have to also purchase 2 wireless cards which makes it a bit cost prohibitive at this moment. Another question.... to anyone.... SInce I already have the cables ran I was using with the hub.... will those same cables work for the router? Also.... once hooked up to the router... will the 2 computers still be able to share files and printer as i have been doing? Last question for this post...... I noticed a few SMC 7004VBR Barricade Cable/DSL Broadband Routers being offered on Ebay. Do you have an opinion on this one or another one as to being the best. Probably the most I would ever have networked is 3 computers.. only the 2 for now. Thanks again!!

Anser to the first two questions is yes. I have had exceptionally good luck with SMC routers. Some readers have reported problems with the ABR versions. Mine are older. I have installed one ABR for a customer and it has been working fine for months. Larry

I have noticed versions with "ABR", "BR", and I believe "VPN".
Do you have an opinion as to which is best? Which is the newer ones?

BR is the oldest. My network uses a SMC7008BR which is the 7-port (7 PC ports plus one WAN port) version of the SMC7004BR. It has operated 24/7 trouble free for a about a year. I used a SMC7004BR for a couple of years and it was a very good router. The ABR models replaced these routers. One of my customers is running the 4-port model of the ABR. It has been operational for a few months without a problem. Info on current SMC routers is available at http://www.smc.com/index.cfm?action=products_choose_product&cat_id=4&prodCat=Broadband%20Routers. I have also tested the 4-port Linksys router. My accountant’s Linksys router has performed very well for over a year. Larry

Well Larry, I must thank you again for your help on this matter. I have just hooked up an SMC700ABR 4 port router and have been successfull with both computers in under 30 minutes. I am in business!! Just a couple of more questions.... 1) It is safe now to discontinue paying for my second IP address from COX? 2) Do I need to continue to use my Zone ALarm Firewall, or is the one built into the router sufficient? 3) Is there any further configuration needed for either question 1 or 2 now that both computers are up, on the net, sharing files and printer....? Thank you once again! Tim

Tim, Sorry to ignore this one for awhie....vacation, Yes you can quit paying for the 2nd IP. Your router will protect you from most incoming connection attempts, since your NAT address is not accessable from the internet. Zone Alarm will protect you from programs that "phone home" without you knowing it. There is no harm in still running it, you will have to map to your other computer so you can still share files. Zone Alarm Does a great job blocking access to your other machine unless you specifically tell it you want to talk to the other box. See the ZA directions on how to set this up (you may already have that done, since you already had an in house network)

You are welcome.

>2) Do I need to continue to use my Zone ALarm Firewall, or is the one built into the router sufficient?

Barricades have been a suffucient firewall for my network for over four years. I see no need to have anything else running. Larry
