Hi i live in a 2 story house and i want to get repeater seutp so that i can have wireless access way in our up stairs the problem im facing is that i cant get my two wireless routers to talk to each other... i have a comtrend router ct-5361t and a netgear wndr3400 dual band router. The Comtrend router allows me two options as far as i know an access point and a wireless bridge both i can add a mac address to and my netgear router allows me to have it as a base and or connect to a base but when i configure it and get it setup it will be good for a few minutes and the computers will jump the the 2nd router and act like i dont have internet on the one how can i fix that?

Power settings, placement (various sorts of interference) can cause problems. I'd suggest moving the AP somewhere, even just a little bit, and test. Play with the antenna(e). Fold a piece of card stock and set it behind the antenna(e) and point that in different directions.

You may do better running Ethernet cable from the Netgear to the other AP.

But generally speaking you run a CAT Cable from one of the LAN Ports on the First Router to the Uplink Port of the second to get Routers to Extend the range of the first WiFi.

These devices do not communicate with each other over a WiFi Link as the second unit isn't a WiFi Repeater it's a Base Station. ;)

I ran across these papers for extending the wireless networks.

thought that may be usefull to you

key points:

??? First Router
o 192.168.1.1
o DHCP to use the range 192.168.1.3-192.168.1.254
o A wireless channel like 11
??? Second Router
o 192.168.1.2
o DHCP is disabled
o Identical wireless security setup as First Router
??? Except the wireless Channel. Try channel 6 if the first is 11.
o Plug hard-wire into the LAN port, not the WAN port.

hi,

depending on the setup, The above is method i use, i have used to extend an ISP's wireless router signal (ie fios ), If your using 2 of the same router that support "repeater mode" (ie netgear 3500/3500l series for example))
then you only need to have the master router connected to the ISP's modem, the 2nd (slave) router only needs to be within range of the master routers signal (a decent strength) and follow the instructions on what to set in each router to enable repeater mode.
here are the instructions from netgears 3500 series router

http://documentation.netgear.com/wnr3500/enu/202-10305-01/WNR3500_RM-06-18.html

Setting Up a Repeater Unit
Use a wired Ethernet connection to set up the repeater unit to avoid conflicts with the wireless connection to the base station.

Note: If you are using the WNR3500 router base station with a different model wireless router as the repeater, you might need to change additional configuration settings. In particular, you should disable the DHCP server function on the wireless repeater AP.

To configure a WNR3500 router as a repeater unit:

1.If you are using the same model of wireless router for both the base station and repeaters, you must change the LAN IP address for each repeater to a different IP address in the same subnet (see Using the LAN IP Setup Options).

Note: Failing to change the LAN IP address will cause an IP address conflict in the network because the factory default LAN IP is the same for both units.

1.Check the Wireless Settings screen, and verify that the wireless settings match the base unit exactly. The wireless security option must be set to WEP or None.
1.In the Wireless Repeating Function screen, select the Enable Wireless Repeater Mode radio button.
In the Repeater IP Address field, the router's IP address is automatically filled in. This IP address must be in the same subnet as the base station but different from the LAN IP of the base station.

1.Fill in the Base Station MAC Address field.
1.Click Apply to save your changes.
1.Verify connectivity across the LANs.
A computer on any wireless or wired LAN segment of the wireless router should be able to connect to the Internet or share files and printers with any other wireless or wired computer or server connected to the other AP.
