R6400 slow internet

I am having extremely slow internet speeds thNetgearhe netgear router I just purchased.  

 

the wifi and lan speeds are just crawling.  I replaced a 4-year-old router that was running much faster via lan and wifi.  

 

Is slow internet speeds a known issue with this Netgear router?  Any ideas how I can fix this?  I have a job and a family so I don't have a ton of time to tinker around with my LAN.

Re: R6400 slow internet

Hi @sb123,

 

1. Please check your connection while bypassing the router and connected straight to the modem.

2. What is the firmware version of the router?

3. You can try resetting the router.

4. You can try changing the MTU. The links below may help out.

Re: R6400 slow internet

Router Model:  R6400 AC1750

Firmware:  V1.0.1.20_1.0.16

 

I encountered the same issue after upgrading to the latest firmware.  WIFI connection became very very very slow and unreliable.  I downgraded to version V1.0.1.20_1.0.16 and it seems to have helped, although the WIFI is still slow compared to before I upgraded to the latest firmware.

 

I suggest to downgrade and see how that goes.  Make sure to reset your router first before downgrading.
