R6400v2 AC1750 Smart Router is slowing down my internet speed

[JJhebert]

My R6400v2 AC1750 Smart Router is slowing down my internet speed, purhchsed in 2019.

Firmware Version V1.0.4.120_10.0.91, 

I confirmed that Spectrum is providing 110 Mbps to my Modem, but speed test only show 50 mbps. 

I was getting 100 mbps up until a week ago, did nothing, but it has dropped. 

I tried resettingt to factory settings. But I think it updated to latest Firmware version

Netgear said I need to buy a Tech Help contract to get help.

Can anyone help me with this???

Thanks

How are you testing speeds?

Wired? 

2.4gh? 

5ghz?

What site are you using?

What device are you testing on?

2.4, ookla , server is on portland maine where I live Using an old ASUS A750 laptop 

I use to get 110 mbps on it

[JJhebert]

I have Lenovo for work, 5G connection, it's only getting 20mbps, but I suspect becasue we have a lot of security software

I tested via cable to modem got 110 mbps

2.4ghz is sensitive to interference. I haven't seen many devices other than AX devices hit 100mbps over 2.4ghz. 

My AC systems usually hit around 30mbps sustained with peaks of 60-70mbps. 

You can try changing what wifi channels its broadcasting on. try 1-6-11. 

Is your work laptop using a vpn? 

do you have a different device you can test both wired and the 5ghz off?

Thanks, I logged into my router, could not find where I change the wifi channel?

I am not using VPN on the 2.4 machine,

How do I change the wireless channel on my NETGEAR router? | Answer | NETGEAR Support

I am not using VPN on the 2.4 machine, -----Thanks. Reason I ask is 2.4ghz is slow. And VPN's can slow down connections. Thats why I was checking if there was a different device you could test 5ghz on. As well as if you can test your wired speeds. the wired speeds will determine if the router is functioning as it should.
