Hello everyone and thank you for taking a look at my post.

I have an ASUS RT-N66U router and a Belkin N750 DB Wireless Dual-Band USB Adapter.

I am using the 5 GHz band because I'm the only one in my building that I'm aware of using it. Normally my speeds are great, but occasionally my latency or ping dive bombs. My download upload remain almost the same, but the ping goes up 20x at least. Even connecting to the router as admin to reboot or change settings becomes very slow. Which leads me to believe its a problem between the router and my adapter. Other devices on the 2.4 GHz band do not seem to have any trouble.

If I simply disconnect and reconnect to the network, everything is fine again, but this still creates issues when I'm on skype or playing an online game.


I am using latest firmware and drivers.

Thank you very much for any assistance!

Please let me know if any more info would help.

I have put pictures of router settings below. Also settings on Belkin adapter are as follows:

Adhoc support 802.11n : Disabled
IEEE802.11h : Disabled
Multimedia/Gaming Environment: Disabled
Radio On/Off : Enable
Roaming Sensitivity: 2.High
Wireless Mode: Both

Thanks for the response. There is not trouble accessing router wired. I'll give your suggestions a shot. However, those were the original settings that I changed in an effort to try and fix the problem. When you say that the dongle is getting hot and cutting? You mean the USB adapter? The connection doesn't cut just slows down.

 
Running at 20mhz channel is the correct way when you are having issues. It reduces the exposure to radio frequency interference because you are using less. It does also reduce the throughput but this is a fixed reduction not one that occurs at random times.

Try to turn the radio power all the way up to 200mw. There really is not reason to run it at less...other than if you were trying to avoid interfering with other devices.

I do not see the actual radio channel on this screen. The safest ones are the bottom 4 and the top 5 (if they are allowed in your country). The rest (between 100-140) are subject to some strange restriction that they must detect weather radar and turn themselves off).

Your problem may be that a neighbor has a 802.11ac router. You will not see these unless you also have a 802.11ac device. These devices use blocks of 4 channels. This means 2 people can use all the safe radio blocks..ie the bottom and top groups of 4. It can also be a bunch of other things like cordless phones etc etc.

What is strange is a reboot of the router will correct this. If it was interference you would think it would stay. Then again if you have it set that way the router maybe changing channels on reboot.

Hi Bill,

Thanks for the input.

I only have a choice of control channel 36 40 44 48 so I have set it at 36. I don't even need to reboot the router to correct he problem. I simply disconnect and reconnect my computer to my network and it is solved until it slows down again. I'm not ready to mess with the power settings, but I'll consider it as a last resort.
