Slow WiFi speeds
I have the Cox plan 300 Down, 30 Up. When I am connected to the network by Cat 5 I often get 300+, 30+. However, when I am on my WiFi, even when directly in front of the modem, I am under 100. I used to get 330+ through WiFi, eve with multiple phones/computers connected.

Do I have the wrong modem/router? Should I look for a different set-up.

Currently have an Arris SBG7580-AC

ARRIS SURFboard (32x8) DOCSIS 3.0 Cable Modem Plus AC1750 Dual Band Wi-Fi Router, 1.4 Gbps Max Speed

re: Slow WiFi speeds
Ignore that 1.4Gbps max speed, it's really meaningless.

Are you sure you are connected to the 5GHz channel?

re: Slow WiFi speeds
I'm connected to the 2.4, but my surface has always connected to the 2.4

re: Slow WiFi speeds
I switched it to the 5GHz and was able to get 250, which is reasonable for the number of devices connected. But is it odd that the speeds will drop by 1/3rd if I move from 5 to 2.4?

re: Slow WiFi speeds
I would say no, with 2.4 you generally get extended range but much slower speeds

re: Slow WiFi speeds
2.4 is much slower, longer range. 5 ghz is faster with less range.

Always just keep your main browsing devices on 5Ghz.

re: Slow WiFi speeds
Check the firmware on the Netgear..I have an "older" one like that too and its starting to cut out, etc...

re: Slow WiFi speeds
My experience is similar. I assume there is just a lot of interference on the 2.4 band because of devices putting out their own Wifi on the same channel (PS4, Lightify controller, etc.) I just use the 5G band and manage to still get at least 50 down at the furthest corner of my lot.

re: Slow WiFi speeds
2.4MHz has a max throughput of about 75Mbs. Actually, in the real world, it's more like 45 to 55 Mbs. And that's standing right next to the router. 5.0MHz has a max throughput well over 600Mbs at close range.

So, the very first thing you'd want to do is ensure that you're connecting to the 5.0MHz radio. Some routers have the bands split. Some, like ours at AT&T, have the bands basically "meshed" so that you see the 5.0 when you're close, and the 2.4 when you're farther away.

To the best of my knowledge, Cox doesn't do anything like that. Most of their setups that I've seen had the bands separately named, so you can choose whichever one you want. To be clear, I've never worked for Cox, and I only see their equipment when I'm removing it during an ATT install. So, YMMV.

Once you've established that you're on the correct (5.0MHz) band, you will want to ensure there's nothing out there sucking up bandwidth. No TOR files getting uploaded, no home security system uploading video, no server farm hiding in your back bedroom. Then, assuming that you've connected to the correct band, eliminated the possibility of network congestion, you can take a look at possible 5.0MHz interference.

There are a few cordless phones that I've seen which can cause interference. Nearby aquariums (weird, I know) can cause wifi problems. Fluorescent lights also and mirrors(!). Assuming you've eliminated all of these potential interference sources--and assuming the problem is duplicated across multiple devices--then you can pretty reasonably conclude there's a problem with the router. Especially if you're getting the speed you're paying for when connected via hardwire.
