Have an EDIMAX range extender. Extender showing connected to router with no problems. Tried connecting my tablet and mobile to range extender and both come up with "Authentication Problem" Wireless Mouse AmanStino ML11 2 4G Cordless Mouse with USB Nano Receiver...

because it is an extender,you need to connect to the modem with an lan and then you can use the wifi

Hi there! Please note that the Tenda 150mbps Wireless Range Extender A3 uses a default IP address of 192.168.0.254 - you must set your IP address to the 192.168.0.* range (* = any number between 2 and 253) to login.

The default access username / password (if required) are admin and admin.

Once you've logged in, you can configure the access point to route through your existing wireless router as the default gateway (eg. if your wifi router is 192.168.1.1, then you would route through that, and set your Repeater (Extender) IP to 192.168.1.2 so that you can connect to it and then "relay" your connection through the repeater. It doesn't mirror the connection details for the existing wifi router, it simply creates an "additional" access point to connect through to your existing wifi router - creating a bridge, essentially.

The extender can be linked to the existing wifi router via LAN cable or WDS. For WDS, you will need to set the IP's 1 digit apart in the last segment (see above IP difference), and switch them both in the Wireless menu to ""Wireless Networking Mode: Network Bridge (WDS), but the SSID must remain the same (eg. "Tenda1") for both of them (it doesn't cause a network loopback), and any wireless security authentication must be identical (password / pass phrase / key + encryption algorithm) on both devices. Again, as with the above point, remember to set the gateway of the extender / repeater to that of the primary WiFi router.

Plug it in to power, then put it a lan cable between edimax and PC, then keep pushing the wds button in extender about 20seconds, then you're done but then you should set it up from the begining here is a link on how to do that. Edimax EW 7438RPn V2 N300 Universal Smart Wi Fi Extender Access Point

Do you have the range extender set up on the same live in the fuse box? If you have the one side on a breaker on the opposite side of the fuse box from the othrr side, it will not work well at all. That is why I encourage people not to waste their money on these things and get a decent wireless system so that you dont have problems.

Apple have produced a downloadable app for managing this router.
It also acts like a signal strength meter, and can control various modes on the extender.

Check there is not a scheduler or "Good Night" setting on the extender.

Poor signal strength:
0 - 39%
So your problem is still poor signal strength, your extender is still not within the wireless range or your router.

A router is only used to connect devices together in a LAN (local area network). In order to get out to the internet you also will need a modem (cable or dsl depending on your service) You will also need to pay for service through an ISP (Internet Service Provider)

You once have to check once that which operating system you are using and check the DHCP and firewall Settings too. You may also check Linksys router support here you get more about Routers.

I have reseted the router configuration back to Factory Default, and set it up again from the beginning. I think the problem was at the firewall settings.
