LAP1142N w/ a Linksys WRT1900AC

lynn77581 · ‎01-18-2015

Recently I replaced my ISP equipment with a Linksys WRT 1900AC wireless router. When I did this I lost connection to my LAP1142 that acts as a repeater. I can assign a static IP address of 10.0.0.3 255.0.0.0 and use the GUI interface, but when I select DHCP the AP is not seeing my router.

I think the issue is the SSID / Password, but I can't figure out where to make this change in the GUI. I don't mind making the change in the CLI, but I don't know the commands.

Any ideas?

Thanks

Lynn

Pls attach your 1142 configuration in .txt format (show run output in CLI) to have a look.

Then we can suggest you to modification required to change to see if the password is the issue.

I have played with this config several times and can't seem to get it right. I am trying to configure this LAP1142N as a repeater.

It should be noted that I am configuring this 1142N on a laptop via the blue Cisco console cable (for the CLI portion) and a cat5 cable (for the GUI portion.).

Here is what I have done so far...

Looks like previous root AP (which you replaced) configured as RADIUS server for the 1142. On your new WRT1900 how did you configure your home SSID ? Did that configure with WPA2/PSK ?

Rasika

lynn77581 · ‎01-19-2015

The SSID on the 1900 is set to WPA2 Personal.

I was up rather late last night trying to figure this thing out. After becoming very frustrated with the config, I looked up the directions on your website and reset it to default using the mode button and loaded a blank config file. I manually set the IP address on the various interfaces. My internal ip address on the 1900 is 192.168.1.1 and it is also serving as my DHCP server. I have it set to issue out IP DHCP addresses starting out at 192.168.1.100. I also do not have VLANs turned on.

Now I have it configured like this...

I would suggest this in that case.

1. Delete the existing configuration & Relaod. If they promp to save config say NO.

erase startup

reload

2. Create a sepeare SSID on your 1900 for bridge 1142 to 1900, this SSID does not need to broadcast as it will only used by 1142 to 1900 back-hall.

In my config I use this SSID only in 5GHz, so WRT1900 advertise this on 5GHz.I used <Bridge> in below config, but you can change it to any-name you like.

Then do a config like below on your 1142. Make sure <HomeSSID> & <HomeSSIDPW> is the same SSID & PW you configured on 1900 for your wireless users.

hostname 1142R
!
dot11 ssid <HomeSSID>
   authentication open 
   authentication key-management wpa version 2
   guest-mode
   wpa-psk ascii <HomeSSIDPW>
!
dot11 ssid <BRIDGE>
   authentication open 
   authentication key-management wpa version 2
   wpa-psk ascii <BridgeLinkPW>
!
interface Dot11Radio0
 encryption mode ciphers aes-ccm 
 ssid <HomeSSID>
 station-role root
 bridge-group 1
!
interface Dot11Radio1
 encryption mode ciphers aes-ccm 
 ssid <BRIDGE>
 station-role workgroup-bridge
 bridge-group 1
!
interface BVI1
 ip address dhcp

Hopefully this should work. If you want you can connect wired device to 1142 as well in this setup. Refer this for more detail

I followed your steps and even reviewed your webpage (which is very informative). In addition to that I looked up this article

http://kb.linksys.com/Linksys/ukp.aspx?pid=82&vw=1&articleid=29317

for the proper steps in setting up the 5ghz channel as the wireless bridge. Once I complete the steps mentioned in the article I receive the same error that is located at the bottom of their web page. It reads... "Unknown Connection Error... Not connected to the upstream device...etc".

I gave Linksys tech support a call and I knew more than the person who answered the phone.

Here is the AP config file with the SSID information included. Do you see anything that stands out as not being correct?

Once again thank you very much for all your assistance.

EDIT: The Linksys WRT1900AC is the only router I have on this network. When I try to put it into bridge mode I think it is looking for an upstream router to connect to. All it needs to do is connect to the LAP1142N so the network will be extended.

EDIT #2: As I sit here looking at the CLI of the 1142 it is telling me that the "Interface Dot11Radio1, cannot associate: No Response"
along with 2 other error messages. I am thinking the issue is on the WRT1900AC with the 5ghz channel not broadcasting correctly.
