TCP/IP Protocols?

(I'm not certain this is a software question. Please let me know if it isn't.)

I recently installed a secondhand Japanese wireless router, Aterm WARPSTAR, on my desktop. I'm having trouble connecting on my laptop. When I open Windows on my desktop I get a message telling me I don't have TCP/IP Protocols on my computer. Would that be stopping me from accessing the internet on my laptop? What can I do to remedy this?

 

I have no experience with Japanese routers, but they may use a different protocol than USA router which may not be installed on your machine. However, it may be that the protocol software on your machine is damaged.

This will definately impair your computer's ability to use the internet, as TCP/IP is the protocol websites use to transmit their data.

Like I said before, since I live is the USA, I only have experince with USA internet. I don't know if it is different in other countries. Where do you live?

 

Actually TCP/IP is what every network that uses IEEE standards, which is virtually every network, use to communicate with other computers and networks. its not just for websites or america, but everything on a network and everywhere in the world that uses computers. tcp/ip is used world wide, as it is standardized by the IEEE.

i posted in the networking section about her issue as well.

 

I figured that was the case. I would lean more towards data corruption. Try running a chkdsk c: /r in a command prompt and see if there are any errors.

 

First i would see if you can hard wire in. Then to down to Starbucks (or anywhere that has wifi for free) and is if you can use the wifi there. If you can't sounds like we need to do some tcp/ip work.... repost after you get to do this.

 

Sorry I'm so late in replying. It takes a lot longer to do almost everything because my Japanese reading skills are not hot so I need to get my Luddite husband to interpret everything. Frustrating to say the least!
Anyway, I'm having no problem with internet access on my desktop but the laptop is having problems. One might be that the (secondhand) router is password protected but the old password isn't working. I had assumed that this was the problem until I realised I was getting a message about missing protocols. Any ideas how to reset a password on a wireless router?
I ran chkdsk c: /r and there didn't seems to be any errors, thgou the screen closed before I could read all of it.
Hard wiring in is no problem. Will head down to Starbucks as soon as I get the chance.

 

Oh and I live in Japan. Laptop has Japanese OS and router is also Japanese. My PC has an English OS.

 

Check the properties of the wireless adapter and see if the TCP/IP protocol is included.

If it is, you could try a couple things. Delete the protocol and reinstall or try resetting with the netsh command. Here is a link for the use of the netsh command - LINK

If the protocol is missing, just use the Install button to add it.

The Warpstar is a NEC product. You should be able to find some information on the router at the NEC site under support options.
Hope this helps.

 

on resetting the router.... you may find a reset button on the back.... use a paper clip to push and hold it for 5-10 sec..... should reset it to factor defaults... if you need a password you need to look up the manual for it. (most have a default password/username) GL:wave

 

Ok, I tried to check the properties of the wireless adapter but it doesn't seem to exist. Under "Local Connection Area Properties" all I've got is "Realtek RTL8139 Family PCI Fast Ethernet NIC" , which I'm assuming is my original whatever it is, router? modem?
I did run the installation disc for the wireless router but it doesn't seem to have stuck.
I'll try resetting and doing it all again.

 

This adapter is on your laptop and is the wired adapter.
Let's back up and look in Device Manager at Network Adapters.
START > Right Click MY Computer > Select Properties > Hardware Tab > Device Manager > Network Adapters (Hit the + to expand the list)
Any ? or ! indicating problems? If not, right click for properties and look for the same things I previously posted.

 

Ok, did that but the only thing still coming up is "Realtek RTL8139 Family PCI Fast Ethernet NIC" (This is on my PC btw)
The Warpstar is there under all programs but not under Network adapters.

 

You won't have a listing under Device Manager for the Warpstar. The only thing installed would be the connection software for it, which would show up in Programs.
What are your computer specs - Manufacturer, Model and operating system?
If it worked wirelessly before and there is no listing in device manager, something has deleted/disabled your adapter for whatever reason.

 

Ok, turns out the laptop keyboard was in number input mode. I didn't realise this because all I tried to input was the password which came up on the screen as dots. I reset the router, changed the keyboard mode to letters, put in the security code on the back and now it's telling me the WEP key is incorrect. Also, do I need to set up a network? Should I repost this in networking?

 

The WEP should have been set to nothing when you reset the router. Then again, there is nothing preventing a router manufacturer from having a automatic default WEP.

What you can do is log into the web interface of the router. You have to wired directly into the router if you cannot connect wirelessly. You just have to open a browser window and go to 192.168.1.1

If that does not take you there, open a command prompt and type in ipconfig. Type in whatever is under default gateway into a web browsers address bar.

The default username and password should be in the manual if you have it, but it is usually admin/admin or admin/password or even admin/1234.

At this point, ever router is different. However, if you go to the wireless section, you should find an option to set the WPA and WEP keys. Set them to what you can remember and then you should be able to connect wirelessly with that key.

 

Tried to reset the WPA key. Still not having any luck. I think I'm going to try again with another router.
