Modem Router Dropping Speed. Netgear AC1750 Wifi Cable Modem Router C6300v2

[Sotelokid]

Recenlty bought this modem and ive noticed my speeds will drop. When i do a reboot my speeds will come back up 200mbps+. Not sure what is going on but ive checked to make sure things are connected and what not. Once rebooted itll be good for like a day or 2 then till drop down to about 1.5mps to 4.5mbps. Any answers or replies will be good. I have comcast as internet provider. They tell me everything is good on their end. Tried netgear support but nothing yet...

speeds drop over wireless, wired, both? Or 2.4ghz/5ghz? Details are important since we aren't there.

when it drops, do you still pull full speeds over wired? 

Do you have a screen snip of the cable connections page and logs? 

I'd also recommend if you have any splitters, amplifiers, or attenuators in line to remove them from the coax line.

They drop on both ....wired and on wifi. its odd and yes let me get a snip and  i will post again. Thanks for replying !

Any Wifi Neighbors near by? If so, how many?

Have the ISP check the signal and line quality UP to the modem.

This is what i got.

I forgot how to check that again..how do i go about ?  My isp told me everything was fine on their end, but of course they say it must be soemthing up with my modem.

If you have a android pad or apple pad you can install a free wifi analyzer there product app store and see what wifi neighbor signals are near by. Sometimes having lots of other neighboring signals can cause problems.

The t3 timeouts you're getting tend to be line issues. 

If you have any splitters, attenuators, amplifiers connected to the coax line, I'd try removing them. I'd also recommend moving the modem to directly where the coax enters the home. This prevents wiring within the home from being the issue. Also check the coax for damage, corrosion, kinks, bad/cheap connectors. 

If none of this helps, the isp should check the line.

Be sure your using good quality RG6 coax cable up to the modem.
