Upgraded WiFi Speed
I have a nighthawk R8000 router. I recently upgraded my internet speed from Charter from 50mbps down/5 up to 100 down/5 up. The two 5ghz connections the router creates are getting the additional speed, but the 2.4ghz connection is not. Even though we doubled our speed through our provider, the main 2.4 ghz network is still topping out at like 45mbps on one of my computers and like 65 on the other. I tried calling netgear, but was told it would cost me $40 to get help that way.
When I bought the router, the box said that the 2.4 ghz band was capable of speeds up to 600 mbps. Does anyone know how to get the 2.4 to deliver the additional speed?
Re: Upgraded WiFi Speed
The 600 Mbps speed advertised by Netgear requires 3 conditions to be satisfied:
- The client's Wi-Fi adapter must support a non-standard, proprietary modulation scheme (256-QAM). Netgear calls it Turbo QAM. I've only heard of one adapter that supports it, the Asus USB-AC56, but there may be others.
- The client's Wi-Fi adapter must also support 3 spatial streams with 200 Mbps per spatial stream. The USB-AC56 only supports 2 spatial streams.
- 40 MHz channels must be used. 40 MHz channels are very difficult to get working. Wi-Fi devices are required to use 20 MHz channels whenever neighboring Wi-Fi networks are present.
It's very difficult to satisfy all 3 conditions, so while 600 Mbps is technically achievable, it's mostly a marketing number.
If you are getting between 45 Mbps and 65 Mbps with your computers, then it's likely that they have 802.11n Wi-Fi adapters that support only one spatial stream, with 20 MHz channels are being used. Unfortunately, this is about as fast as you are gonna get with these adapters. If you can provide the model numbers of the adapters, I can look up their specs.
You may be able to eke out 10% more speed by enabling Short Preamble mode in the Advanced Wireless Settings of the R8000 and your Wi-Fi adapters. But, really, your best bet is to upgrade to dual-band Wi-Fi adapters, preferably 802.11ac, and connect at 5 GHz.
