Finding network, but no internet

[nahlgren]

I'm trying to set up a new computer to my wireless network, the router is a dlink DI-624+ and the network adapter is a dlink DWL-g122 (choosing to go all one brand to make sure things play nicely together, in theory anyway). The computer is finding the network as it should, and can connect to it, but not to the internet. The problem appears to be not getting an IP address from the router, using ipconfig tells me my ip is 169.254.15.XXX and not the 192.168.0.XXX it should be. There is also no sign of any standard gateway. Using a regular network cable there are no problems, so I am at a loss on how to solve this, as was the dlink support people I've talked to.

If anyone can shed some light on this I'd be grateful!

The router assigns the DHCP information when you are connected via Ethernet cable? OK this is slightly a rant on my part. I have been a fan of DLink for quite awhile, but the past three devices I have purchased from DLink were bad. Not a fan any more. Your challenge it to decide if the router or the client adapter is indeed working wirelessly. Is there any way you can test either device with some other equipment. From what you said my first inclination would be that one of the devices is defective.

Also if the client is not getting an IP then the wireless connection is not OK, it could be many things that are causing that. Do you have any firewall or security applications active on the computer?

[nahlgren]

I've checked that both devices work as they should. I've had the network running on another machine for a year, using the exact same set up, so I simply swapped the USB adapters and the new card works on my old computer but the old card doesn't work on the new computer.

There is no firewall in place, I've disabled the windows one, and I've yet to install anything new.

The problem was apparently that I needed to upgrade the router's firmware, doing that solved everything. I find it a bit strange that the dlink phone-support didn't suggest that when I was in contact with them, but...

Thank you for letting us know how you solved it. I then suspect that the firmware load on that particular unit was corrupt as the existing firmware should have worked. When you loaded the new firmware it then replaced the bad sections. Interesting and not something one would suspect form a major supplier. Bit of a quality control problem going on.

Hi,

I'm having a similar problem and would really appreciate any help anyone can offer.

My setup: ADSL line to modem which is connected via Cat5 cable to router, which in turn is connected via Cat5 to a desktop. I'm trying to share this connection with two wireless enabled laptops.

The desktop has no trouble connecting to the internet through the router, although ipconfig /all reveals that despite being connected to the router, it is still using the IP address assigned by the ISP (82.243*.*) and ipconfig /release and renew does not change this to one in the router's range (the router's homepage is 192.168.2.1).

For ages now I've had the problem that the laptops can detect the network but can't access the internet, and I've been trying and trying to sort it out. I thought I'd managed it last night when I actually got to my homepage, but ipconfig /all showed that my laptop had basically 'borrowed' the 82.243.*.* address from the desktop which was disconnected, and hadn't been assigned a 192.168.*.* address. This obviously means that only one computer can be online at once or you get the old 'XP has detected a conflict with another system...'

ipconfig /renew does nothing to change this, and I just can't see where I've gone wrong. I've been all through the configuration interface of the router - in the NAT section I told it to translate the 82.243 address to addresses in the range 192.168.2.2 - 254 (to be honest, I'm not entirely sure how it works, I just assumed...) but no change. In addition, I can only access the configuration interface if I manually assign an IP address to the laptop within the router's range, but this prevents me from getting on the internet! Running the XP network diagnostic tool when I manually assign an address comes back telling me that everything passed except for the DNS server numbers, despite the fact that the same DNS servers work when I 'obtain an IP address automatically' and am given the 82.243 address.

I was worried at first that it might be my hardware because it's actually a modem/router combined (I'm just using the routing function - I need to keep the original modem as it also connects to the tv and phone), but surely the fact that I can connect through the router (albeit with the wrong IP address) means that it's working? Any ideas?

Thanks in advance

Where in the router are you connecting the cable from the modem? And does the router have a RJ45 Ethernet port for the WAN/Internet Interface or a RJ11 connector. It appears that you are just using the switch portion of the router.

[Libatius]

The Cat5 from the modem is plugged into one of the four LAN ports on the router. There is also a socket marked ADSL which fits an RJ-11 cable.

thanks for replying!

That is the wrong kind of router then. You will never get it to NAT or give out DCHP leases. It will just act as a switch and that is why you are getting that IP address from the modem and it will only allow one lease at a time.

[Libatius]

Perfect - is that because it's supposed to be used as a modem AND router at the same time, and can't function just as a router? The manual says it's supposed to provide IP addresses from 192.168.2.2 up to 192.168.2.255...

[M/Q]

It will as a DSL router. A router's main job is to take two different networks that will not negotiate any kind of communications and translate the traffic between them. Your router is designed to take DSL network traffic and then convert it to Ethernet traffic. Then along the way it will act as a DHCP server as well.

I guess I am not quite following either as you should be able to replace the existing modem with the DSL router you are referring to if you have DSL Internet.

[Libatius]

I know, ordinarily I would just remove the first router from the equation...basically, the adsl line from the wall connects to the modem, which in turn connects to the computer, the tv and the phone (one of those bundle deals). If I remove this modem and replace it with the modem/router combo i lose tv and phone (unless you know a way round that!).

To add insult to the injury of just finding out I've wasted money on a useless router, I've just discovered, completely by accident, that my magic 'all in one' box, not only does internet, tv and phone, but also...wireless NAT routing if you activate it - going to try that... So, firstly, sorry for wasting your time, and secondly, thank you for trying to help - I really appreciate it. definitely the most informative forum I've tried.
