New Laptop No Internet Access via Wireless

[npttrs]

I have recently purchased an HP Dv8 series Laptop and a Sony Vaio laptop. THe same issue is on both so I presume that they both require teh same solution.

At home I have an Intellinet MIMO Turbo G Router which is connected to my computer (also Windows 7 64bit) via a lan cable. The Router is secured via a WPA preshared key + you need to add the mac address for people to access the internet

I want to connect the laptop via wireless internet and I have done so successfuly on XP and Vista before on other laptops. This new laptop has Windows 7 64bit. I put in the mac address and the key, and it connects to the Network. It says that it is connected, but when I go to Wireless Network Connection Status, it says that IPv4 Connectivity: No Internet Access
IPv6 connectivity: No Internet Access
Media State: Enabled
SSID: default

On the bottom right hand corner, the wireless icon has a yellow triangle over it. When I try to troubleshoot it doesnt find anything.

What can I do to solve this?

typically when that happens it means authentication failed the router will allow you to connect to it but it won't give you network access.

Is the MAC address definitely right in the routers whitelist?
Did you definitely type the WPA key correctly?

 

[npttrs]

Yes both are correct. I retyped them both in the router page.

Just for giggles, try disabling your MAC filtering for a minute, see if that fixes it. It will at least narrow down the problem area

 

[npttrs]

Well you did fix it so thanks a whole lot for that, but how come the mac filtering doesnt allow it to work?

 

[severedsolo]

really? :shock: awesome!

Honestly I wasn't expecting that to work... I thought the problem would be with the WPA key.... If I were to hazard a guess i would say your wireless card doesn't report its MAC correctly to the router... just a guess though

Not sure if this will help, but on my router I had to go in to it's settings and clear the old laptop out along with other devices I don't use anymore and restart the router so it could locate the new device. Once I did that my wife's laptop connected right away and was good to go. I had gone over the device limit for the router, but never took the devices out as I got rid of them (2dsi's and the old lappy) Just a thought

Geeve

Edit: Just saw you fixed it, so never mind

the wireless card is an Intel Wifi Link 5100 AGN. The same issue is on my other Sony laptop and I can probably predict that the internet now works there too since it showed the same symptoms. So its gotta be some default settings on the Win7 laptops,

If I have the WPA key, is my internet connection safe enough without the MAC address option? I mean if it works like this and there is no danger then I will just leave it at that.

 

[severedsolo]

Honestly, I would leave it as is. WPA is secure. theoretically it can be hacked... but the efforts you have to go to do so are just not worth it. there are easier targets out there. you will be fine

 

[npttrs]

alright well thanks a lot for your help. I just checked and the internet works on the sony laptop too. Its very odd that mac filtering had to be turned off but I guess if its not really broken then I wont try to fix anything.

Again thanks

Mac filtering is a new one on me and I'll have to remember that in case it comes up again. I have the Mac clone option but never needed to use it, not sure if I have a Mac filter or not.

Ok just found the setting and it relates to security. It says that with Mac filtering ON and allow computers listed to connect. Mac filters ON and denie computers listed to connect. Kind of confusing. Seems like this one should be off as default.

So you can filter it either way it seems or just set it to the OFF postition and have no Mac filtering at all. I just needed to hit advance wireless then the network filter tab.

So the new computers would need to be added to the list in order to keep this setting turned on. No wonder the Op needed to add the Mac address manually before. This might actually be a useful security feature if you were having problems with someone hacking through your WPA security. I have 24 computers I can add to my list.

Honestly I think that MAC filtering is overkill. A strong WPA key is almost impossible to hack using a dictionary attack (which is the only way they can be got) It certainly has its uses, but a MAC address is easily cloned. anyone who knows how to get through a WEP key probably know's how to clone a MAC address too

 

[chev65]

I'm not sure cloning would be enough. From what this setting showed me there was no way to get a mac address with this setting turned on because it requires an authenticated DHCP computer name to be on the allowed list. It pays to use a seperate password for the router set up page also.

I wouldn't know how to hack past WPA either, depends on the password I guess. What I'm wondering is how could this setting have been turned on by default? Talk about confusing. Maybe a reset of the router would have got this setting back to normal. I always keep a .gws file on my desktop in case I need to reset my router, gets all my settings back instantly that way.

With the right software, you can pick up the MAC address of all devices transmitting in range. then with WEP/WPA hacking software you can "spoof" your MAC address to look like one of the machines that is authenticated.

Example: I know your WPA key, but you have MAC filtering on. With this software i mentioned (obviously I won't mention any names) I can "spoof" my MAC address to look like yours. when the router asks for authentication my wireless card transmits your MAC address. the router thinking that I'm you then allows me access

 

[chev65]

Yes but it also requires a singular DHCP computer name not just the mac address in order to be issued an IP, or at least on my router it does. It would at least slow them down a little but seems hardly worth the hassle I agree. I doubt I could hack into my own system even if I tried LOL.

:roflmao: By DCHP name do you mean the machine name? for instance on my PC Martin-PC?

As you may be able to tell... I've actually experimented with this stuff to test my own defences. WPA just would not fall, as I have a mixture of letters and numbers in my passphrase WEP... now thats a different story

Yes but they would need to get into the router and put the name on the list which requires hacking into the router as well. Come on now, I'm no dummy, anything can be hacked, I'm well aware of that. Did you really think otherwise? I only mentioned it as an extra layer of security, never said or mentioned about it being unhackable. Please spare me the inuendo. :sarc:

 

[severedsolo]

your router sounds like it has very strong defences... most routers as far as i'm aware just rely on MAC checking when it is enabled

 

[chev65]

Not that routers are hard to get into but I use a different 12 digit password for my router that isn't in a dictionary. It has a list for those mac addresses plus you need the DHCP assignment name on the list next to the correct MAC address,so if the name and the Mac address don't show up right next to each other the list then wireless DHCP won't work. Still I agree 100 percent, nothing is unhackable but I sure wouldn't know how to get into this one. Seems overkill to me.

 

[severedsolo]

thats quite unusual. Here's mine, as you can see it just looks for MAC addresses, so a spoof would fool my router quite easily.

Of course I also have reserved addresses from the DCHP pool so i imagine that would create a conflict as the router would be trying to give it an IP address that has already been issued
