Here's a little networking puzzle for you guys.

Ok I'm using a D-Link DSL-504T modem/router for my home LAN. Just recently bought a Netgear WGT624 v3 wireless router and connected it to the dsl router, for my wireless gear.

Just an hour ago mate of mine had problems connecting to his msn account via wireless off his laptop. After running a few tests his laptop can't connect to the msn live messenger server but can contact 'em via tools > options > connections > advance settings > TCP test, and is also having troubles loading myspace.com. Any other net activity is working fine.

I then connected the laptop to the netgear router via ethernet cable and tested msn live messenger and myspace.com, as you can assume both are logging in and loading fine.

My question is, has anyone had experience with this weird problem? According to the OSI Model the application should not SEE or care wether it's an ethernet connection or a wireless connection. Any help would be awesome.

P.S. the netgear and dlink router's firewall settings are pretty much default.

the main problem I see people have when thye have a modem/router + wireless router is that they don't configure them correctly which can cause issues. But usually it's just a matter of whether they can get an internet connection or not.

How have you got them set up?

Make sure that both routers haven't got dhcp on. In fact, I find the easiest thing to do is turn dhcp off on the wireless router. Then make sure you have an ethernet cable going from the modem/router to a regular port on the wireless router. I'm not sure if that netgear has an "internet" port (can't be fucked googling)....if it does, don't use it.

I also make sure I Repair the internet connection just to make sure.

None of this will probably help, but meh, I felt like posting :P

What Justo Said

As in, make sure the modem has DHCP, and that the Wireless Access point doesn't, and is set to bridge the connection.

Also, try entering a manual DNS server in the TCP/IP settings, 61.88.88.88 works for me

Yep, as stated, one of the biggest issues is people having two NAT'ing routers connected, one behind the other, and things get a bit screwy.

It' sstill a little odd that MSN/myspace aren't working, but the setup IS broken, so it's worth fixing.

Turning off DHCP and using a non-WAN port on the wireless router is a little bit of a kludge, it essentially turns the wireless router into an access point, which is fine, it's a perfectly reasonable network layout, even if the manner in which it's achieved is a little strange.

What I would consider to be the "correct" way of doing this would be to put your ADSL router into bridge mode and then configure the wireless router as a PPPoE client, having it manage the connection/authentication, etc. (Bridged mode essentially turns the DSL router into a straight ADSL ethernet modem.)

Alternately, if the wireless router actually has a proper configuration option to make it act purely as an access point, doing that and leaving the DSL router as is would also be fine.

Good luck. :)

That's the thing, these things *should* work. But to me, it just adds one more thing that *could* go wrong. And then you factor in sometimes dodgy compatibility between different brands....so I find it best to keep things simple ;)

+1, netgears and dlinks are bastards to deal with unless their firmware is at least from the last 3 months IMHO.

given you were able to perform some connections over the wireless (did I read that right???) I suspect you may have a throughput problem? Try a continuous ping from your friends laptop to the gateway on the modem with different size payloads and see if you get a reply to all of them (ping -t -l <size from 1 - 65500> <gateway ip>)

imo wireless is the devil, but there you are...

Yeah, those D-Links can be buggers. I successfully managed to brick one a while back.

Wonderful having to fight over a one port modem/router...
