Model: TL-WR820N

Hardware Version: V3

Firmware Version:

is it true wifi extenders half the total isp speed when extending wirelessly (not using ethernet)? i was planning to buy extender as a cheap alternative to get wifi in dead zones. (So please dont recommend to buy more expensive router or extend a cable to the dead zone.Id rather not do any of these. Extender in wireless mode or no use ) I thought "High speed mode" solved this already. Some say (in other posts) that high speed mode or netgears fastlane tech solves this and extender halving speed was a thing in the past. But then here in these community, many dozens of guys say "extender work in half duplex mode, you're only going to get half of your router speed always".

If this is true

1. whats the use of high speed mode?

2. Why hasnt such an issue been solved these years?

3. Working of High speed mode:> using 2.4ghz and 5 ghz at the same time between router > extender > client (dedicating one of the band between both). So doesnt this solve the issue of speed getting halved?

Who's wrong???

@Rozin8

Full-duplex is what most wired connections use which means two devices can send and receive data at the same time and can also detect collisions straight away via CSMA/CD.

With wireless connection (half-duplex) devices cannot send and receive simultaneously and they cannot sense collisions. Instead they use CSMA/CA to detect usage on the frequency to see if it is safe to transmit data. There are a large number of factors that can affect a wireless signal and interfere with it which results in lower throughput.

So yes, you'd get around the half of the wireless bandwidth advertised.

High speed mode:

"The High Speed feature switches off one of the wireless bands to leave one high-performance, super-fast network, ideal for HD streaming and gaming applications.

If most of your devices are connected to one wireless band, this feature can increase the overall performance of your wireless network."
