What customers say about "Key Specs"
TP-LINK TL-WA830RE Wireless N300 Range Extender
  • Nice... it works beautifully and now I have wi-fi coverage all over the apartment!. Can even get it out in the parking lot.
  • This is also my fourth use of a range extender and it is clearly the best.
  • If you are not receiving the full strength of your wireless signal, you need to purchase this range extender.
  • The only downfall is that it seems that I have to reboot it every couple days.
  • Failed to meet expectations in terms of adding wifi coverage.
TP-LINK TL-WA850RE N300 Wi-Fi Range Extender
  • My room is in the attic, the router is downstairs, and it has boosted my PS4 speed from 8gb to 30gb!!! It even has a very handy app!
  • I performed a few internet speed tests with SpeedCheck Pro and wow... my internet speed had increased from about 3-5Mbps to 20-30Mbps.
  • I can wholeheartedly recommend this device and although nowhere do they advertise that it increases internet speed, in my case it certainly has.
  • Vastly better than devices using our house's (modern) wiring, both in terms of ease of setup and signal strength/ speed.
  • Using an online speed test I measured an increase from 26mbps to 97mbps so has proven to be very effective.

What customers say about "Features"
TP-LINK TL-WA830RE Wireless N300 Range Extender
  • I consistently get 25 Mbps ~ 30 Mbps download speed from directly plugging in the Ethernet cable to the Motorola SB6121 SURF board Cable Modem.
  • I have a media player plugged into the ethernet port on the back of the extender, and areas where we had 1 bar to no signal are receiving full or almost full bars.
  • The indicator lights helps a lot in determining the optimum distance between the router and the modem.
  • The extender is easy to install. But the indicators go orange and red every few hours.
  • Even with unit right next to wireless router, signal strength led indicated no signal strength from router half the time.
TP-LINK TL-WA850RE N300 Wi-Fi Range Extender
  • Excellent product. Easy to configure with the "Tether" app. Just follow the instructions on app as you go.
  • I had to use the app on my phone to synce it which wasn't a problem.
  • If you don't have a cable, an App on your phone should allow you to perform a step by step setup.
  • Blue lights do shine very brightly at night which is a bit annoying.
  • Interestingly the TP-Link app sometimes says the signal is weak between the router and extender, and at others says it's perfect, even though neither has moved or is obstructed.
