I need an indoor range extender for a "dead zone" about 20-25 meters from router. I bought  RE2000, however it did not solve the problem, because:

a) if it is connected within the recommended range from router it does not amplify the signal enough

b) if it is connected i dead zone area (20-25meters from router + obstacles like walls) it does not catch the signal from router

what model would you recommend ? Ar there any models that can be connected further from router or ones that would amplify the signal stronger to reach the dead zone ?

thank you
