how to fix the default getway server for internet sharing in a small network using a router and a hub.?

Find the wan ip address of the router (for eg. it may be 192.168.1.1) set this address as the default gate way in your computers.

Port forwarding only works from OUTSIDE your network. Not inside.

To start off with.  Are we 100% sure that these devices are routers, and not switches.  8 port routers are not uncommon, but not as common as 8 port switchs. \nIf it were a switch, and only one computer was grabing the ip address from the modem, that would explain why only one computer could get online at a time.  I have seen switchs work with two computers for a short time before.  Afterwards, you will get a message, "Limited or no connectivity"  at the bottom of the screen.  Also, if anything has changed, that would be helpful to know.  Did you just switch from Cable internet to DSL?  Or did you change out the DSL modem?  If the DSL modem was changed out, and not put in what is called bridgemode, this problem may not come up as an issue until all 3 computers are actually on and trying to access the Internet.  (Putting the modem in bridge mode tells the Router it is in charge of establishing the credential info w/ ISP, not the modem.  If modem is in charge of this, it may only have the ability to handle one computer on the Lan side of the network.)\n\nLet's start off and assume that you do have routers.  Here are some things to check:\n1.  is the router plugged into a Uninteruptible Power Supply? (I have seen many drop off and connection issues solved with this little piece of heaven.  I know you are sceptical about purchasing new hardware, but this should be a pre-requisit for all devices that have any kind of value.)\n\n2. If you are cabable I would read the instructions for your router, and reset it back to factory settings.  You may want to write down the existing settings before you do this.  (if it is connected to DSL, your username and password, Cable, if it is a static or DHCP wan address etc. etc.)  Once back up and running, download the latest firmware from the manufacturer.  This would require Internet activity.  \n\n3.  As was stated earlier,  let's connect each computer directly to the back of the modem and check for connectivity.  (If the modem was previously set to be in Bridge mode, you will have to change it to be in charge of handling the logon creditials.  This usual setting is PPPOE)\nOnce the computer is connected to the modem, you need to power cycle the components so that they grab new IP addresses from each other.  Power off Modem and computer,  plug modem in first, let all lights quit blinking then power on computer.  If computer is unable to connect, it could be modem issue.  But let's not rule out other things.\n    a.  Check the network settings on the computer.  Right mouse click on My Network Places and go to Properties.  From there right mouse click on the Lan Properties and go to properties there.  Click on TCP/IP and hit the Properties button there.  Check to make sure the adaper is set to obtain IP address automatically.  And the DNS the same.\n\n4.  If all computers are set to obtain an IP automatically as described in step 3-a.  and they are hooked up the a factory default router, with known good cables, they should be able to at least ping each other.  Disable all Norton Internet Security, and Macafee Internet Security and Zone Alarm (Some of these actually block ICMP request so we wouldn't be able to ping the computers)  Go to computer 1 .  Start --> Run. type  CMD and hit  enter. type "ipconfig /all"  leave off quotes  write down the ip address that it assigns you.  If you have the Linksys router setup, and it is set to default factory settings, it will probably assign you an address of 192.18.1.100 or close.  Go to another computer.  Start --> Run  type "cmd" and hit enter.  type "ping 192.168.1.100" or what ever number that was listed.  if you get a reply, that means you are able to pass traffic through the router to the other computer.  if you get request timed out that means you are not able to connect.  \n\n5.  If after reseting the router to factory settings you are unable to ping the other computers on the network, but

Do some testing.  Try http://www.dslreports.com with and without your P2P service activated.  Repeat the test with your computer connected directly to the high speed service.(without the router)\n\nProve that this is the router!\n\nGood luck and Happy Computing

do a tinternet search on\nbt home hub port forwarding ;)

you can always use a router or you can buy a lan adapter. it's like a lan hub

well u can share internet in win server 2003 . well step is below\n\n1) start dns server\n2) start dhcp server\n3) then configure Remote and Route Service in that u  \n   select NAT service\n   but for that u need two NIC (Lan Card)\n\nif u didn't get me then tell me i will explain in detail

...this is a toughy, but i would initially guess that the problem is with dhcp assignments... is the router using dhcp?

check your IP  configuration it sounds like you need to make some adjustments.  The computers were never configured on a private network were they? How about the router have you configured that? See if the PC is getting assinged and IP address by the router. Go to start menu, select run, type cmd, then press ok, then in the dos window that opens type ipconfig and press enter.  Does it come back with your IP address, etc.? What does the default gateway say?

When you get an IP conflict like the one you have described, there is an other router in the aria with the same IP... You will have to do a serch for wireless networks, then delete all but yours from the list....

Well, one way you can fudge it is like this:\n\nroute add -p 0.0.0.0 mask 0.0.0.0 1.2.3.4\n\nwhere 1.2.3.4 is the ip address of the gateway.  This assumes that there is no gateway already in place.  With this done, you should be able to get remote desktop access from across the network so you can go in and correctly set the default gateway using the appropriate configuration tools.

I dont want to re-invent the wheel. \nhere's the link that'll explain better\nThis is assuming that you have WINDOWS XP HOME EDITION OPERATING SYSTEM\nhttp://www.microsoft.com/windowsxp/using/networking/expert/bowman_02april08.mspx

You don't need a HUB, that's what the Switch is for.  It's a smarter version of a HUB.  Hook all of your equipment up and then run the Network Set Up wizard in windows.  I would run it on your server first and then the other machines.  Make sure you write down all of your information and input it EXACTLY the same on all machines.  It's called the Network Set Up wizard in XP, I don't know what it is called in ME, but it is there.  Just open up My Network Places to find it.

Turn the firewall offf. Your router acts as a firewall and will conflict with the router...

The cheapest one would be a second hand one, which you could pick up at a local computer show, or on eBay.  Brand names will usually add money to the final price, but the difference might be $5-ish.\n\nThe real question is: Do you need a full fledged router?  Depending on what you wish to do, you might be able to get by with a hub or intelligent hub (if you just need to link PCs together.  If you really need packet management capabilities, perhaps a switch would do.  If you have spare PC's lying around, you could turn one into a passthrough traffic server.  Lots of options with PCs.  Post another question with the specific configuration, and perhaps we can help you out.

i hve a linksys as well and have no trouble with wep.  in theory, enabling wep should only affect wireless traffic (not the net connection), so I would check to make sure you have the internet cat5 in the right plug then take it back and get a new router- if you're good at this stuff then configuring wep shouldnt do anything bad- assume it's bad hardware once and give it a go w/ another unit.

Please check if you have dynamic ip address in your TCP/IP settings. And LAN settings should be set to automaticlly detect settings. :) Sometimes you need static ip to work, by changing the ip add to 192.168.0.1 and subnet mask to 255.255.255.0, and the leave the gateway blank.
