5GHz visible channel range problems

FPSUsername · July 7, 2015

Hello,

I want to speed up my 5GHz by selecting a higher channel, but my usb wifi adapter only reaches till channel 48 (which is on the low side).

My stuff:

Modem/Router: Cisco EPC3928AD

USB Wifi: Edimax AC450 (Drivers v5.1.19.0)

Phone: Samsung Galaxy S4 GT-I9505 (This device can see all the channels, so I can verify they should work)

These are the settings that I can apply at my modem/router (Radio Settings):

Wireless Interface: Enabled/Disabled

Network Mode: A only, N only, A/N mixed

Channel Width: 20MHz only, Auto (20 or 40MHz)

Channel: Auto, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136

Extended Channel: 44 (This depends on the channel that you've chosen)

SSID | BSSID | SSID Broadcast

5GHz| MAC adress | Yes

These are the settings that I can apply at my Wifi usb device:

AP Mode Force BW20: Enable/Disable (Not sure what it does) (Default is Disable)

Country Region (5GHz): #0 (36-64, 149-165), #1 (36-140), #10 (36-48, 149-165), #11 (36-120, 149-161), #12 (36-140), #13 (52-161), #14 (36-116, 136-165), #15 (149-173), #16 (36-173), #17 (36-64, 132-140), #2 (36-64), #3 (52-64, 149-161), #4 (149-165), #5 (149-161), #6 (36-48), #7 (36-165), #8 (52-64), #9 (36-116, 132-165) (Default is #0 (36-64, 149-165))

IEEE802.11h: Enable/Disable (not sure what this does too) (Default is Disable)

Multimedia/Gaming Environment: Enable/Disable (Default is Disable)

Radio On/Off: Enable/Disable (Default is Enable)

Roaming Sensitivity: 1. Highest, 2. High, 3. Medium, 4. Low, 5. Lowest, 6. Disable (Default is Disable)

Selective Suspend: Enable/Disable (Default is Enable)

Selective Suspend idle timeout in seno: 1-60, I've put 1 in there. (Default is 5)

I've tried to change the Country Region (5GHz) to other values, no luck there. I don't know how to get it at a higher channel without dissapearing from my laptop's usb wifi adapter.

Any help would be appereciated.

It could be the limitation of the wifi dongle. To get faster speeds on wifi you need to choose the higher channel width, the higher you go the faster the connection speed, also some 5Ghz has a drop off point at about 5-10 feet.

AP mode is for when you are connecting to a wireless router/wireless modem and then devices can connect to the AP(access point) The wifi dongle should be AP mode on for better signal strength as it is, i assume, connected to the router/modem and you are connecting to the dongle. I would connect to the router/modem and forget the dongle thing.

Enable IEEE802.11n for faster speeds but this is for n/ac devices only.

Multimedia/gaming is your QoS, Quality of Service for less buffering for internet intensive programs like streaming and games.

Radio on/off is for broadcasting the SSID or not. If you turn this off you will not see your SSID in your wireless scan and you will/may need to add your AP manually for you to get connections. Cisco's firmware is weird like that.

The roaming sensitivity is for the antenna signal strength of the wireless signal.

You want N only for network mode if all your devices have wireless n capability.

My sister has an S4active and her modem is not wifi so i changed her router to AP and connected it to the modem and she can now get +600mpbs speeds when i select channel width of 1300mbps on the 5Ghz band.

Hope i made it clearer.

DDWRT people for best user interface.

Thanks for making it clear. I have turned off multimedia/gaming since it generates a lot of lag (internet lag) in games (weird though).

I think it is a limitation of the AC450, it works well with N only at channel 45.

I have more settings to set at 5GHz:

Transmission Rate: Auto, Use Legacy Rate, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 32

CTS Protection mode: Auto, Disable

Beacon Interval: 1-65535 (is at 100)

DITM Interval: 1-255 (is at 1)

Fragmentation Threshold: 256-2346 (is at 2346)

RTS Threshold: 0-2347 (is at 2347)

I know that I didn't have transmission rate 32 (6 Mbps) before, maybe because I switched to N only now.

I should try it I think.

Edit: Nice it works

I've seen somewhere a table with the speeds and 36-48 are the slowest class, I think mine cant get past there. It doesn't find 52 so I think this is it.
