Bought used R6100, problem with 5GHz Wi-fi on PC

[vortexmak]

Hi,


I bought a used R6100 off Craigslist, it's a AC 1750 router. It works well for the most part but I've noticed that Speedtest.net from my PC (Azurewave 802.11ac card) sometime shows about half of the speed than my Galaxy S4 which also has AC wifi. It also fails to loads pages sometimes when my phone at the same location is able to load them fine.
I usually have to switch to the 2.4 GHz network and switch back to 5GHz to fix it.

One observation is that Wi-Fi Analyzer on the phone shows -45 dBm signal level vs -60 dBm reported by iwconfig on my PC which is strange cause the phone would have a much smaller antenna

Any way I can fix it diagnose what the problem is?

Hi...Please let me know the current FW version. Latest public version is v1.0.0.62.

Just updated to this latest version. I will check the performance and update this thread

EDIT: I am still facing issues. Every now and then internet stops working, Wifi remains connected though. I have to switch to the 2.4 GHz SSID and switch back to 5 GHz to make it work again

Chrome shows this message
DNS_PROBE_FINISHED_NO_INTERNET

Is there any way to check the router connectivity logs?
The logs on the Admin page are no help

EDIT2: Looks like the problem is limited to my desktop with Linux Mint 17. I don't know if it's my Azurewave wireless card or the OS. However, I never had problems with any of the three Brighthouse supplied routers before. It's just this with Netgear that this problem has been consistent.

NETGEAR_Guy are you aware of any wireless problems with Linux?

I'm not aware of any specific issues with Linux...will check with the support team

Is the Azurewave wireless adapter updated to latest drivers?

Try disabling N mode in your Linux distro and see if that helps. I had this issue recently on Linux Mint 17 & Ubuntu 14.04 with two laptops using Intel 7260AC as well as two using Intel 6230abgn on both 2.4/5 Ghz bands where it would drop out every 20 mins or so. Problem seems to be gone for me now though. I don't think its completely a Netgear issue, may also involve Ubuntu upon which Mint is derived. There were quite a few others in the Ubuntu forums with similar complaints and with different routers.

Try this to disable N mode and see if it helps, you can still use G & AC modes:
sudo sh -c 'echo "options iwlwifi 11n_disable=1" >> /etc/modprobe.d/iwlwifi.conf'

Thanks for your replies everyone.
Turns out, problem was with the router. My Windows laptop also kept dropping it's connection.

I wasn't able to detect it initially since the problem was intermittent but pinging the router continuously made it clear.
