wifi question

Hi, I just bought a sweex wifi adapter for the pc of my son which has win98 on it. I did confure the adaptor and the connection strength is good but when I go to the dos prompt to see which ipaddress I have I get a ipaddress that starts with 169.. and I get that address for both adaptor because there is also a build in wired adaptor in the pc which is not being used. I did ipconfig /release_all also release with the nr of the adaptor but it won't release it. Now win98 is old and I can figure things out better in XP now but can you help diagnose the problem? How can I release the IP I see....

You should be able to connect more than one.  Is the router also the wifi access point or do you have separate devices?  Can you connect more than one computer by ethernet cable (i.e. wired) and have each of them get a valid ip?

Hi sharscho,
Why is there a problem with the IP that starts with 169?

Scott AndersonPrincipal Support EngineerCommented:
You can't really release the 169.254.x.x IP your are getting because it's being assigned by the OS (APIPA).  The 169.254.x.x range of IP's was chosen by Microsoft to be "self-assigning" IP's for Microsoft OS's, beginning with Win98SE.
A Windows OS will assign the NIC a 169.254.x.x if the points below are met:
 - NIC is in Enabled State
 - Senses media connected (RJ-45 cable)
 - Does not have a static IP assigned and cannot locate a DHCP server

What is your wired NIC plugged into?  Does it do DHCP (Dynamic IP address assignment)?
Is your Wireless NIC configured to associate with your AccessPoint?
  and is your AccessPoint or some device on your network handling DHCP?

sharscho,

IPs that start with 169 are in the autoconfiguration range and basically it is an ip the computer assigned itself.  Completely useless in a LAN or WAN environment.  Do you have a router?  Does it assign IPs?  If so make sure the TCP/IP protocol for that connection is set to obtain the ip automatically and does not have one assigned.  If the router does not assign IPs or you don't have a router then you will need to enter the IP address in the properties for the TCP/IP protocol.

If the Wifi hub/router/AP has security enabled then make sure that you have set this computer up with the proper key and/or set up the hub/router/AP to allow the computer (i.e. if MAC filtering is enabled).

Let me know more details about the set up if this info doesn't help.  If you need details on any step I mentioned then just let me know.

Let me know if you have any questions or need more information.

Hi b0lsc0tt, My router does assign ip and the adaptor is set to obtain ip. What I did when I configured this adaptor was selecting WEP encryption and then entered one of the keys available. router is not set to clone mac address. How do I get rid of the 169 ipaddress, I think that is causing the problem. If you need more details, please let me know.

b0lsc0ttIT ManagerCommented:
It is a symptom of the problem and why you can't access the LAN or Internet.  The cause of the problem is the router is not giving you an IP.  Try reentering the WEP key.  You can even delete the connection from the computer and type the key again.  Don't just enter one of the available keys but make sure it matches the one the router is set to currently use.  They only use one at a time so if you pick the wrong one you will still get rejected.  Then restart your computer to see if the ip matches the range from the router and not an auto config one.

Let me know if you have any questions.

So even if I see 4 keys on the router I have to enter the first key-> key 1 on the pc because it always uses one key? how do I get to know which key it uses?

b0lsc0ttConnect With a Mentor IT ManagerCommented:
You have to use the right one.  The default is the first key.  On that same page you should see a setting for the key to use.  May be a group of radio buttons or a pull down list.  The description for that setting is different depending on manufacturer (i.e. transmission key, etc).  If you can't find yours then please let us know the make, model and version of your router/AP.

If no computer is able to get a valid IP then I would recommend doing a soft reset of the router.  This is usually done by sticking a small pointed object in to a recessed hole to press a hidden button.  Just press it quickly and release without holding it down.  That is the common way to do a soft reset and there may be some issue with the router.  That almost always will fix it.

If other computers (i.e. wired or wireless) are able to get a valid IP from the router then that probably isn't the issue.

What range of ips or how many is the router allowed to assign?  Are you at that limit?  Usually this is at least 20 so I doubt it is the problem but the setting may have been changed.  You could look at it if the other options haven't helped.

OK, I get an ipaddress now. I used the first key of my router. I have a linksys wireless router. when I do a ipconfig /all I see all the good settings but I can't pass beyond that. I can not get on the internet from that pc. What is the prblem now?

b0lsc0ttIT ManagerCommented:
In the ipconfig /all results do you have DNS server(s) info?  Can you ping the router?  Can any computer get to the Internet?  What does the router have for DNS server?  The best set up for the computer is for it to obtain those automatically too.

Another question:  how are you getting internet access - DSL?  Does your Internet Provider require a login/password to access their system?  If so, you'll need to set that up in the router, also.

Hi, I did get internet connection and so the 2 problems above has been resolved BUT when I have my laptop from which I have a vpn connection through wifi, the pc in which I added the sweex wifi adaptor does connect anymore. I suppose that I can connect more than one device to this wireless router through wifi. Why can't I connect 2 pc's in this case? What settings should be changed in the router to allow this. I don't want to go and change and lose all connections I have now but I can only connect one device at the time now and not simultaneously.

Yes I can, I have 2 pcs connected through a wired network cable and I also can connect 3 through wired without problems. The problem is connecting more than one through wifi. The router is the access point. I have a cable modem that is connect to this router and from the router  connect other pcs to get to the internet.

Thank for the reply.  I did understand the problem but wanted to see if it was just wifi which you have answered.

Did you try the soft reset of the router/AP?

Hmmm Has this something to do with the fact that all the pcs I want to connect through wifi use the same key? Does the router accept only 1 key at the time?
0
 
b0lsc0ttConnect With a Mentor IT ManagerCommented:
No.  Yes, in a way.  The router will only use one key at a time but it can accept multiple connections.  In other words usually there is a place on the router to specify a few keys (often 4).  There is also a place to tell the router which one to use.  That key needs to be used by each computer that tries to connect.  They will be rejected if the key is wrong or if they use a different key but that does not limit the number that can use the correct key.

Oh OK. I understand. But do I have to specify in the router the number of wifi connections are allowed then? because I find it strange that when my laptop is on, the pc is not able to connect and what I see is that it gets to the router but not beyond. Maybe I should have say that also because I see that getting to the router is one thing and getting through the router is another. I see that the pc has an ip address but I can not get to the internet if my laptop is connected through wifi.

What make, model and version is the router?  This all may be caused by settings to allow VPN.  In general you do not have to specify the number of wifi connections to allow but your router may have some setting for that.  How is the VPN set up on the router?

I have a linksys router model wrt54g wireless broadband. All settings of the vpn tab are enabled. I saw that 1 key encryption is allowed.... But there are so many settings that I would not dare to touch. Maybe the model of the router may give you a clue...

What version of that router?  What is the firmware version?  Is it up to date?

Have you tried a soft reset?  I haven't seen that you responded to that question yet.  If you need details about doing it then let me know.
