Netgear C6250-100NAS AC1600 WIFI speeds are very slow

[vageeshgovi]

My Netgear wifi speeds have suddenly gone very slow. Right now the speeds are at 0.07mbps while I should get over 100mbps. I tried reselecting the channels various times and factory reset the router as well. Need help!

Have the ISP check the signal and line quality UP to the modem. 
Be sure there are not coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem.

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

Try testing with a different wifi device to compare.
