Linksys Wireless DHCP problem?

Q. I have two laptops that don't seem to reliably receive an IP address from the router, or they lose it after a short period of time, and then they cannot reconnect to the network ("limited or no connectivity". However, I have a third laptop that has *never* had a problem connecting, or staying connected. Connecting via ethernet always gets an IP. All are using XP Pro with all updates applied.
I am using a Linksys WRT54GS and WAP54G both with the most recent firmwares. I am using WEP only (no MAC filtering). I have updated the drivers and the management software on one of the problem laptops. I have tried different channels too. We are able to connect reliably to neighbors' networks, but I hesitate turning off security altogether. The WAP is in repeater mode; I have read elsewhere that each AP should have its own SSID - that struck me as incorrect, but the suggestion also indicated that having the same SSID would cause "confusion". The router has been swapped out (other prob)
DriftRB- tried/verified those, but problem persists. I was able to apply a static IP, but there was no 'connectivity'

KH - That's what I read in the manual too - WAP in repeater mode will only connect to a WRT54G router

Also, just to see, I turned off WEP & problem vanished.

Thanks for the help so far!

A. 1. Make sure that your DHCP range is large enough to support 3 laptops, i.e. you will need min of 3 address available.

2. DHCP may not be releasing address and then failing to reconnect each time you connect these laptops filling up your available connections.

3. Make sure DHCP is supported in your TCP/IP Properties.

4. Make sure that the LAN IP of the DHCP is added to the safe zone on your fire wall.

5. Do Not use Static IP in the DHCP range on these laptops, remove all static IP address's unless you have assigned these with the MAC address on the DHCP


Note - Locking Address to Laptops using a Static DHCP address for MAC Address of the Laptop could resolve this issue



FOLLOW UP (11:55am 10/10/2007):
Sorry if I confused about the static IP's. You want to have computers in the network to get the IP address from the router.
Remove the static IP's from the computers and enable the DHCP server on the router.
After doing this, reboot the computers and this should be working.


NAT for Xbox Live is strict.?
Q. My NAT is strict. How can I change my settings to open without breaking anything? What does open mean exactly?

P.S.: I have a WAP54G linksys router, could the newest firmware fix my problem?

A. You need to connect to your router through you pc and change it, read the instructions for your router.
Your ISP has nothing to do with it.


Why can't I access the setup page to my LINKSYS WAP54G ACCESS POINT?
Q. i am trying to access the set up page per my wireless WAP54G access point so that i can upgrade the firmware but i can not. all firewalls are off including anti virus ..... i have check tcp/ip properties which are set to automatic.... yes i have tried to connect the access point directly to the my computer via Ethernet cable. then went into internet explorer to access 192.168.1.1all and it gave me the following information:

IP Address. . . . . . . . . . . . : 68.197.116.241
Subnet Mask . . . . . . . . . . . : 255.255.252.0
Default Gateway . . . . . . . . . : 68.197.116.1
DHCP Server . . . . . . . . . . . : 167.206.245.76
DNS Servers . . . . . . . . . . . : 167.206.245.130 & 167.206.245.129

i even tried accessing the default gateway (68.197.116.1) above and that does not bring me to the setup page of my access point. please help
I JUST TOLD YOU I RAN IPCONFIG AND IPCONFIG/ALL READ 1ST THEN ANSWER...

A. um you do realize exposing your IP to the world is NOT a good thing...

What do I need to do to connect a Linksys WAP54G and Linksys WRE54G to a Motorola SBG6580?
Q. The SBG6580 is my cable modem/router/wireless access point. I'm trying to connect the WAP54G to the SBG6580 and the WRE54G to either the WAP54G or SBG6580. I've changed the two Linksys devices to use the 192.168.0.x IP and I have the wireless settings configured to the same SSID and channel. I've tried various security configurations as well as no security, but nothing
seems to work. Which MAC IDs do I need to have in the SBG6580 and WAP54G? I'm also reading some things that say that I need to call Motorola to use the SBG6580 as a bridge. I don't think that's what I'm trying to do since the SBG6580 is the central point of my network. Please correct me if I'm wrong. Thanks!
@K, Yes. Wireless was set up using the CD. I can connect wirelessly just fine from all my wireless devices except for the Linksys network devices. Basically, I just need to know which devices need the MAC IDs entered to make the Linksys devices work as a wireless bridge to the SBG6580. Thanks.

A. Well the first question is was the SBG6580 set up for wireless using the cd?

Check the link below for an informative discussion. I hope it helps you to some degree.

**edit**
Mac Addressing:
I am assuming your SBG6580 is "the first in line" with the cable connection and in behind it are the two Linksys devices and you want the Linksys router as a bridge (confused by this but see link #4).

Putting the Mac ID's on 2 devices (cable SB and router) should work fine, wired Mac address for the appropriate machine(s) and wireless Mac addresses for wireless devices or both. (The Mac addresses are different for a single computer and change dependent upon if the connection is wired or wireless.Same is true with other devices such as the Linksys router. [IE: with 3 machines you will have 6 addresses wired and wireless]. I suppose you may or may not know this.)

You can if you prefer only identify by mac address to the appropriate router what is strictly wired and what is strictly wireless. In effect if you identify both wired and wireless address for one computer but its ongoing connection is only wireless, it simply means a wired address specified is not used but authorized to connect.

For strictly wired device only address needed is mac address that pertains to anything that stays wired...computers and/or router. Devices connecting wireless to the Linksys router can be identified to it by Mac addressing as well. Also if any wireless device such as a laptop that may be connected wired or wireless at various time, both Mac addresses for a laptop would need to setup for the device to which it will be wired.
Staying with the 3 machines example, all three have to be assigned within your network isp addressing layout and as identified in the SBG6580 (again assuming it is the 1st in line connecting to the actual cable coming into the location). Don't forget to identify the router with Mac address to the SBG6580. The extender has no Mac filtering and is a bridge in and of itself to the Linksys router from what I've read. Assuming it has a mac address, which I think it may but not certain, identify it to the Linksys router.

Bridging:
I found an older article about bridging the two Linksys devices and updating firmware was part of the solution. I'm posting the article below as it may help you with the bridging issue. I also found a page with instructions for bridging one of the Linksys then ran into this one and as it is about issues with the same 2 Linksys devices..it's just an older article though maybe it will help.
And for good measure check out the tech blog #3 link below another older article. I'm hoping to find something more current.

How to bridge WRE54G link #4

I think this will help all together and makes sense...just keep in mind all computers and router have Mac addresses and need to be identified with wired or wireless OR wired and wireless. Apologies this is so long and I've probably said the same thing several different ways though I hope doing so helps in some way.
