C6220 2.4ghz dramatically slow

Depending upon your wireless devices design and support. most 2.4Ghz wireless will be some what slow. 2.4Ghz will usually not match anything near what 5Ghz performances can do. Noise, Envrionment, device design, and streams will all govern what actual speeds are seen. 

Usually I see anything from 50Mbps to 200Mbps max on 2.4Ghz however thats with a high end wifi router I have and use. I don't have the C series modem though.

Hello everyone,

I am having some trouble with my router and am wondering if anyone has any ideas on how to improve the speed on my 2.4ghz band. My ISP is Xfinity (comcast) and I just had a tech out today to replace the line (had a lot of interference, and it actually did help the 5Ghz side). So with my package I'm getting about 250Mb DL and 15Mb UL on the 5Ghz which is pretty good. However on the 2.4Ghz band the best result I've had is 3Mb DL and 0.15Mb UL on channel 3. Any other channel is around 0.25Mb DL and 0.15 UL. Some tests also indicated that UL speeds were significantly higher than the DL speeds on the 2.4Ghz band. Any help in resolving this issue is appreciated greatly
