View Full Version : Internet Wont Work Unless Router Is Connected
Hi,
Basically im having problems with my internet and ive got an engineer coming out on monday, I do believe its the modem to blame but to make sure I want to do a speed test direct to my laptop etc...
However when I connect the modem directly to my laptop it doesnt work on the internet, I checked and for some reason the Gateway wont show.
If I plug it into the router, it works fine both wired and wireless....
Whenever im changing over and power everything off, do modem 1st then router.
Can someone help me get just the modem working on my laptop without the router?
Thanks,

Have you tried turning, laptop, modem, EVERYTHING off and then connect the laptop to the modem directly, switch the modem back on, wait for lights to stabilise and switch the laptop on. If this doesn't work try pressing Windows + R to open a run window and then type cmd and click OK. In the command window type ipconfig /release, press enter and then after that type ipconfig /renew and press enter
Hmmm...I sometimes get that with my PC but I can just resolve it by turning the modem OFF, then connecting the modem directly to the laptop via ethernet while the modem is still OFF, turning the laptop on (or keeping it on if it's already on), then turning the modem back on and just waiting for a bit.
Try that and if it doesnt work, tell us :)
I followed all the steps and basically it will say "Identifying" for ages then connect to an "Unidentifyed Network" then wont work on the internet. Heres some screenshots if it helps:

Hope I can get this sorted lol..
have you tried clicking diagnose?
Yes, if I remember correctly apart from not fixing it, it says theres nothing to fix lol.
I mainly wanna do this so I can check the speed direct and also use that page to check the signal levels to see if there ok
I just done a speedtest from my laptop there and look:

..... at least earlier I was getting 7Mbps lol
I can check my signals anyway when I am connected via Router. http://192.168.100.1 username root password root
When I go to that address it doesnt ask for a password and takes me right here:

Nothing unusual there from what I can see
I asked this on the Netgear forum and one of the moderators said:
seems the mac address is been reserved the by the ISP system so it will ONLY allowing that mac address (WGR WAN's mac address) to connect to the broadband and get's the public IP.
all these need to be deal with ISP so that they are aware of it. since this laptop and modem directly issue and netgear works so all the question must ask to ISP support. I doubt onsite guy can fix this. If you want put the laptop with directly to modem now to get work. ISP must release the current mac address and hoping that it will get your laptop work..
continue to call ISP support and get that fixed
Surely they cant "make" me use the router :S
I phoned Virgin Media again there just to see if there was anything they could do about the working on router but not on modem etc..... after they put me through about 1hour of boring "already done" stuff what we did was connected it in and it gave a weird IP address, when we connected it without the coaxial cable in it gave a proper IP address, so im going to need to wait for the technician tomorrow.
Does anyone know if these engineers have a good success rate or if its just a case of "ummmm well need to get a part in and ill need to contact someone about this"..... or will it get fixed......
The woman I had this mornin was soo annoying, she wouldnt listen to anything just read off her screen, at first she started giving me reset steps for my V+ Box :S :@

Nothing new, they always read from a script. Some will deter from the script in a real attempt to help you, but the vast majority don't. If you scream and shout enough, they will hang up first by the way ;) As some calls are recorded, it doesn't make them look good!
I'd only have suggested what was said above, it seems strange that your modem won't give you an IP despite a full power down and power up.
They'll probably just replace your modem
I asked this on the Netgear forum and one of the moderators said:

Virgin don't operate like that. The way their system works is that it issues an IP to the first device plugged in after the modem is powered up.
Well luckily I have a friend of the family who is a network engineer for Virgin Media, when the guy comes tomorrow ive to mention him so he doesn't "fob" me off as he put it and hopefully ill get back to my easy 20meg full speed.
Btw if you were to cancell you VM before 12months how would it work, im on my 6th month.
You pay of the rest of your contract, I'm not sure but I think it's £10 per service per remaining month

They might have to change your modem to fix it.

Hi there!
from my what i read, your internet works when your router is connected, but not when you switch to using your laptop directly? even if you power off inbetween?
the modem remembers the MAC address of the hardware which you plug into it to prevent you from hotswapping between router and laptop, all you need to do is power off the modem and remove the router, wait a few minutes, 5 to be sure, this allows time for the modem to 'forget' the MAC of the router. then plug in the laptop direct and power up the modem, and power up the laptop. you will need to go through the same process for every time you switch the hardware connected to the modem.
hope this helps:)
Im sure I tried that m8 but ill give at a go again before the engineer arrives.

OK I done that and it worked!! Yey!..
Now I have just the cable modem plugged directly into my Windows XP laptop which has no antivirus or anything, basically just normal laptop.
Went on Speedtest.net and ran a few tests and got:
DL: 10.14Mb/s UP: 0.72Mb/s PING: 81ms
DL: 16.86Mb/s UP: 0.72Mb/s PING: 80ms
DL: 17.62Mb/s UP: 0.72Mb/s PING: 79ms
DL: 11.49Mb/s UP: 0.72Mb/s PING: 79ms
So its better but should the engineer still be coming out as im not getting 20Mbs constantly....?

EDIT: remove photo link when you read this as your mac address is on it
what you talking about there Ben, thats His Ethernet cards Mac, as in the LAN side MAC, nothing to worry about as No one on the WAN (web)side can get to it or effect it.
as for the problems its simple looking at the second picture, and im amazed no ones picked it up so far, the ethernet cards not getting an auto negotiated valid LAN IP address from the modem....
and so windows is giving a generic and bogus windows ethernet stack 169.* address....that kills connectivity....as nothing else is using that range.... and all your packets from then on try and use that bogus address as the latest default gateway.....
to test this , unscrew the cable coax from the modem but keep the ethernet cable pluged directly into the PC, you Should then be given a 0.0.0.0 then a 192.168.0.* address if the modems working properly AND the PCs ethernet is SET for auto negotiation (obtain an ip address automaticly).
YOU DO have a straight through ethernet rj45 cable and NOT a crossover ethernet rj45 cable dont you, if its crossover your router will be sorting it out the right way but the CM will not switch it back the right way and so no valid IP address is issued, as its not talking to the PC stack through ethernet right...
right you definately have a straight though rj45 cable!, and its still not working direcly connected to the CM , then remove the old ethernet entry device in the networking section of your PC OS, and have it re-find the device and add it back in ... probably as a new No. and it will be set a a genenric 'auto configure' DHCP by defaut and should then start working.... once you reconnect the cable coax and reboot everything in order.....
to simplify,the generic Basic problem is:
its that 169.254.141.130 thats been given by your windows IP stack because its not getting OR understanding any real LAN side IP from your CMs internal DHCPd server...
your directly connected atheros AR8131 ethernet card should be getting the 192.168.0.1 range from the VM CM for its LAN side IP.....
anything 169.* is given by the windows stack AFTER it cant find anything else from a DHCP server somewere on the LAN, usually the CMs internal DHCPd.
until you get a valid 192.168.* address from your CM your directly connected PC will be going nowere, clearly its getting given one when your routers in place, as they usually have auto negotion LAN ports so you can use eather type...
so i suspect a crossover rj45 cable were a straight through one is required for direct PC<>CM connection as the VM CM does NOT have auto negotiation abilitys on it ethernet LAN port and cant use a crossover ethernet cable. OR your OS SW stack is not set right, so delete it and have it auto re aquire the device and generic settings OC

Try the speedtest at the top of the forum. It's a bit more accurate than speedtest.net.
Ok ive had 2 engineers in my house today about it...
Basically they see that im not getting my full speed, it varies from 4meg to 7meg etc... jumps around all the time, they said its nothing to do with my setup and they changed the modem etc.
They said that because its coming up to 4pm they cant start the job just now because it will involve taking out other peoples broadband to sort this.
So I need to wait till tomorrow for them to start the job but they said it could take a few days :(
what you talking about there Ben, thats His Ethernet cards Mac, as in the LAN side MAC, nothing to worry about as No one on the WAN (web)side can get to it or effect it.
No popper, the link was to a screenshot of the modem config pages showing the mac and serial number of the modem.
LMAO!
Right now there even so kind enough to give me 0.56meg :)
Just incase when I move house, is there any other broadband services that give top speeds like VM, my friend has BeBroadband and he says there good.
Now I do seem to get a nice 19meg on speedtests but every 4 say somtimes its down at 12-16.... is that normal or should I be getting a "constant" 20meg?

At peak times 12 to 16meg is probabaly above average. Hell! Lately I rarely see 19meg, not even in the midddle of the night.
