Comcast wireless very slow (wired fast)

by rlaraway1 / March 5, 2013 10:50 AM PST

I have the comcast performance internet and have noticed extremely slow wireless speeds (even when I am right next to the router). These slow speeds seem to often be during peak times (5pm-9pm). I live in a high rise apartment so I am wondering if there is some sort of congestion when everyone is on it at the same time. What's odd is that when wired, I still have good speeds. Here are my specs:

Wired speed: 25mbps
Wireless download: 1mbps
Wireless upload: 4mbps
Windows wireless connectivity : 144mpbs with excellent signal
Router: Linksys E3200 Dual-Band N
Modem: D-Link DCM202 (docsis 2.0)

I am wondering if maybe I should update my modem to the recommended DOCSIS 3.0 but I am not sure if that would help?

Thanks,
Rob

Cable connections are shared w/neighbors

Since cable connections are shared with your neighbors, and as you say you live in a high rise, you're in all likelyhood running into cable congestion. You could try setting your router to another channel or plugging your computer into a wired connections, although it's likely just cable congestion.

It's likely many are using WiFi at the same time and there are few open channels. I doubt a cable modem can fix a WiFi issue like this.

Try another channel or that other 5GHz band your router has.

Changing the channel worked great! I was also wondering very little people are using the 5GHZ band. My router is a simultaneous dual band. Is there anyway to select one band or the other to see which is faster/less congested?

Why?
by R. Proffitt Forum moderator / March 6, 2013 12:46 AM PST
In reply to: Thanks!

Because it's the new thing. Most gear out there is on the 2.4GHz WiFi band as well as reduced range in the 5GHz band leads me to write these are the most likely reasons.

My newer router automatically seeks out a less congested channel but as folk get home, you may have to reboot the router if you are using the automatic method/setting.

I use a small Android app to scan the area. Almost Star Trek like? It's this app.

I'd talk to the wireless router's maker.
