[Solved] Multiple Same Model Laptop Networking Problem

Hello Everyone,

My company, which is small (about 8 people), just purchased three new laptops that we use to connect to wireless. The organization is based in London so we use Citrix to connect to the server there. Our office features a basic Business wireless bandwith through comcast.

Also, our router (I am told) was purchased to handle the workload of up to 10 computers working on citrix at once...but I'm not so sure.

Anyway, the model computers we are using are: TOSHIBA PORTEGE R835's. They are x64 based systems, with good processors (i5 2140m).

Now, often when I log on to the internet using the windows networking service to my Wireless router, the poor girl with the same model computer gets booted. This problem can persist, and only once in a while it works. She reports that everytime I am on the road and not around with my computer, she can log in just fine.

I'm thinking this is a IP issue? some help would be great!

Let me know where I haven't been clear.

Yes, most likely a conflict exists in that your machine connects with the same ip address, so it bumps hers off.

It sounds like your router is not set up with the DHCP function to assign enough addresses, or you are using static addresses that are the same. Connect to the wireless router (type the router ip address or network name from the manual into your browser with correct router user and password) and check the settings for the wireless LAN, including the assignable range allowed to the router DHCP function.

Also in each computer check its ip address assigned by using the command prompt and typing "ipconfig" that will list out the gateway address, machine address and some other information. If they are static you can change them to dynamic and assigned by the router's DHCP function.

To find the router address, just look at the gateway address when you enter "ipconfig" into the command prompt box on your computer. Then type that in your browser, it should be something like 192.168.0.1 or 192.168.1.1 Id is probably admin and password is probably admin, password, <blank>. Depends on the specific router brand.

Turn on all the laptops and then look at the router dhcp ip address table. Insure that they all show up and that the dhcp function has a sufficiently large range of addresses to assign. When the laptops are all on you can also type "ipconfig" in the command prompt of each to see if they have different addresses.

Also insure that each laptop is set to obtain its ip address dynamically from the gateway router, not have a static address on the laptop.

You can also reserve an address for each laptop by MAC address -- you can get the MAC addresses by running "ipconfig" in the command prompt box on each computer. It is a unique id that is six pairs of hexidecimal digits separated by a dash or colon (like a1:c0:ee:67:29:ab).
