diverdriver 7 #1 January 9, 2005 I now have high speed internet with SBC DSL. I have an Ethernet Hub (Netgear EN 104tp). It has four jacks and according to the user manual I have them connected right. What I keep getting is an error with both computers connected to the hub. The error message is "There is an IP Address conflict with another system on the network." I've had this hub in working order with two other computers with no problem. It has sat in a box for a couple of years and now I can't make it work. Grrrrr. Both laptops are using Windows XP. Can you help a brutha out? Need more info?Chris Schindler www.diverdriver.com ATP/D-19012 FB #4125 Quote Share this post Link to post Share on other sites
stardog 0 #2 January 9, 2005 You need to make sure that the hub is acting as a dhcp server. You should have instructions on how to get to the hub interface via web browser. Also make sure that your machine does not have a statically assigned ip. Good luck. Good stuff. Later! Quote Share this post Link to post Share on other sites
CrazyIvan 0 #3 January 9, 2005 Release IP on ALL the computers hooked to the hub. Also, the settings on those systems should be OBTAIN AN IP AUTOMATICALLY, I'm assuming you also have a router, so, the router must act as a DHCP server.__________________________________________ Blue Skies and May the Force be with you.

PhreeZone 20 #4 January 9, 2005 Hub's can not assign IP's, that has to be done a DHCP service. This can either be found on a Router with DHCP or a server set up to do it. Chris, you need a home router to do what I think you are trying to (share the DSL out to multiple PC's straight from the DSL line). A hub will not work.Yesterday is history And tomorrow is a mystery Parachutemanuals.com Quote Share this post Link to post Share on other sites
stardog 0 #5 January 9, 2005 Look at the wireless routers as well. Adds a lot of conveince, pretty inexpensive. Make sure your laptops have wireless card. Quote Share this post Link to post Share on other sites

Chris, I'm seconding what Phree is saying. A decent router will solve your problems, it will also help with your security. You can pickup a decent router (Netgear isn't a bad brand) for under $100.--"When I die, may I be surrounded by scattered chrome and burning gasoline."

salling772 0 #7 January 10, 2005 chris you will need a router. they are down to about 30$. when you get let sbc know and they can help you with the setup. ps. a good router will have a firewall in it---------------------------------------------- All you have to decide is what to do with the time that is given to you.

diverdriver 7 #9 January 11, 2005 Thank you all! It's odd that this setup worked before but now it doesn't. Wonder if the changing OS from when it was up before is an issue also. Same box worked fine without another router. We plugged the DSL line into this router and then plugged our computers into it. Hmmm... I know I'm missing something....

Did you ever have software from the DSL company installed on your system? Is it possible your computer was doing the PPPOE via the OS or the software? I haven't looked at what your router has, but if it lacks PPPOE this could be the issue. Hmmm....just re-read your original problem...this wouldn't be connected to the duplicate IP addy issue unless you only had one computer at a time connected to it before._________________________________________ you can burn the land and boil the sea, but you can't take the sky from me....

jsaxton 0 #11 January 11, 2005 Actually, dhcp has nothing to do with this. you need a device which can provide Network Address Translation. Quote Share this post Link to post Share on other sites

rmsmith 1 #13 January 11, 2005 Hi Chris, DHCP = Dynamic Host Configuratio Protocol NAT = Network Address Translation LAN = Local Area Network WAN = Wide Area Network You should have a (firewall/router) box with two ports, labeled WAN and LAN. The WAN is the untrusted Internet side, and it should be configured as a DHCP client or you enter the fixed IP numbers issued to you by your ISP. The LAN is your home network side, and it should be configured as a DHCP server, and your two PC's should be configured as DHCP clients. Your LAN side should be using a non-routable IP range like 192.168.xxx.xxx, and a subnet range of 255.255.255.xxx,, which is specified in the LAN's DHCP server setup. All setup is usually done from a web browser using an address like http://192.168.1.1 or something close to that...read the manual. Quote Share this post Link to post Share on other sites
Avion 0 #14 January 11, 2005 Phree got it right. Simply put, you need a router. You can get a 10mbaud wireless routers for under $20 now. You'll have to have wireless adapters for the computers too. $10-15 apiece. It can be done in a couple of other ways too. The arrangement you have now will run only one computer at a time, and you would have to turn both off then turn on the one you want to use. If you try to run both at the same time they will conflict with each other and cause a network jam. Depending on you DSL equipment, your DSL modem might also route, you would have to check with you service provider. Be careful, Bellsouth will tell you that you need an additional router for additional cost to do networking when the modem itself has the capability to do the routing if you set it up right. PM me if you want more details. Cheers Quote Share this post Link to post Share on other sites

flyingferret 0 #16 January 11, 2005 Don't forget to consider you ISPs DHCP policy. There is a lot of verbage thrown around in here as to whether or not you have a router or a hub/switch. Based on that, there might a possiblity that you get DHCP addresses from your ISP, not locally. Typically though, ISPs like SBC will only issue one IP, and if they are using PPPOE, you have to use a login to get that even.

PhreeZone 20 #19 January 11, 2005 Localized DHCP is fine, its the dual homing and then introducing the OS as a weakness instead of hardware. It is a hell of a lot harder to get through even the most basic home router then is it about 90% of the home Linux/Windows boxes being used in a dual homed environment. I know a company that has an AD Group policy that says if 2 network cards are online at the same time it is to disable one of them. Dual homing is great as long as you are a tech that knows exactly what they are doing. Too bad that does'nt describe the vast number of people out there.
