R6400/WNDR3400 Wifi isssues
Hi all,
Hoping to get some insight on Wi-Fi issues I'm currently seeing at home. My house is wired with Cat5e throughout. When I plug a network cable into any jack in the house and run a speedtest from my laptop, I get an average of around 50 mbps download, which is the advertised speed I pay for. When I run a speedtest on Wi-Fi, I'm lucky to get 2 mbps down, and this goes for any device (Laptop, iPad, iPhone, etc), and from virtually any location in the house (Upstairs, Main level and Basement). I've included a network diagram below to give you an idea of my setup. I currently have a cable modem in the basement, connected to a WNDR3400 router, going to an 8 port switch, patch panel and then upstairs to a Netgear 6400 (setup as an access point) on the main level and then a Linksys WAP610N access point on the 3rd level. Wireless coverage in the house is solid, it's the connectivity/speed that is lacking. The router and both access points are configured for 2.4ghz band, all with the same SSID and on channels 1, 6 and 11. All hardware (Router, and 2 AP) have the the latest firmware installed. I live in a newer development with a lot of wireless networks, so I've tried different channel combinations all with the same result.
Thanks for any help!

Hi Elaine,
Thanks for the response. I was able to figure out the issue last night and it turned out to be an oversight on my part. I noticed every once in awhile when I was running speed tests on a hardwired connection to a network outlet in the house, the ethernet adapter on the laptop would sometimes randomly enable and disable on its own. I started to put 2 and 2 together and realized it could be a problem with the switch. When I was setting up the switch a couple days ago I ended up using a wrong power adapter that although it fit, it wasn't supplying enough voltage to the switch. Once I swapped over to the correct power adapter for the switch, rebooted everything and tried another speedtest, it was much improved at 35 mbps download.

Hello Lynch30 I suggest that you try to isolate first by determining from signal is giving the 2Mbps.
You mentioned that they are all using the same exact SSID which I assume for seamless roaming.
Turn off all other wireless and verify which wireless device that gives you the low speed.By the way, is this happening on both wireless signals (2.4GHz/5GHz)?
Since all firmwares are updated, did you reset the device after upgrading?
Make sure as well that there are no other device that may cause interference such as cordless phones, microwave ovens, baby monitors and the likes.
