Cisco E2000 Wireless Router - Really Slow Internet

So I have charter 30Mbps internet (I've checked with them multiple times and they say there are no degredations or outages in internet speed in my area). I have a brand new motorola DOCSIS 3.0 modem. And I have the Cisco E2000 wireless router setup for N network only. I've checked multiple interent speeds on all 3 of my computers (all of which are fairly new with wireless N capability. I range anywhere from 0.4 to 3.0 Mbps doing the speed checks. Nowhere close to the charter speeds I'm paying for. I will occasionally get a random spike to 20Mbps or so, but it only lasts a minute or two.

Looking online there seems to be a lot of problems with the E2000 putting out a slow signal. And people change a bunch of random settings on the router ip access webpage. Which settings should I change? They are all default right now. No clue what any of the settings mean. Thanks!

For 5GHz :
Wireless Network mode should be mixed...
Different SSID from 2.4 Ghz
40 MHz wide
Wide Ch 159, Standard Channel 161

For 2.4GHz:
Wide-40MHz
Wide channel to 1, Standard Channel to 11

Beacon Interval to 75
Change the Fragmentation Threshold to 2304
Change the RTS Threshold to 2307

Save and reboot

Have you connected one of your computers directly to the modem and then run a speed test?

Have you connected one of your computers directly to the wired side of the router and run a speedtest?

What type of wireless security do you have on your wifi?

Thanks! How do you even know these settings or what they mean? I'll try these out to see if it improves.

I have connected directely to the modem and get 20-30Mbps consistantly (leading me to believe it's the router). I have the wireless N security enabled (I think it's called WDM or something?). I have to type in a password get access.

You want to make sure you have WPA2 security enabled with a long random key (20+ characters+symbols). Also Turn off the feature called WPS. Unfortunately this model router is vulnerable to the WPS problems even if you turn it off in the configuration page. The good news is on your model it might be possible to flash it to the DD-WRT firmware http://dd-wrt.com/wiki/index.php/Linksys_E2000

It's probably caused by interference by other wireless devices, neighbor's networks, microwave, etc.

Okay, that's what I have enabled WPA2, with a good password. I will turn off WPS as well to see if it improves.

Also try plugging directly in to the router and ensure the wireless is disconnected on your pc.
