Followed the directions and paired it up to my Buffalo modem router and the light on the repeater turned green indicating successful pairing. Now when I moved it to another room and switched it on, it still lit up green but there was absolutely no wifi signal at all! I checked with different devices as stated and only my laptop was able to detect maybe 1 or2 bars of wifi, as it did without the repeater.
So, I decided to reset the repeater and set it up again as it wasn't working in any room and I was not getting any signal boost at all.
After resetting, it just couldn't pair with my router any more. I tried WPS method as well as manual setting up using the repeater's menu. It just started throwing errors that it couldn't pair with the router(on the repeater's page) and the light never turned green. Even WPS method didn't work. I tried trouble shooting it by resetting it multiple times and even unsecured my wifi network completely to see if the security protocols were causing the problems, but still it didn't pair. Now I have a white huawei paperweight with me and it isn't good as a paperweight even as its so light. I hope to return it to mobilefun for a refund, hopefully!
While looking up the problem on the internet, I came across many ppl having problems with this unit and returning it, so I think this unit is defective from factory.
I'd recommend ppl not buy this repeater and look for better alternatives as this comes with free headaches and frustrations bundled with it.
