While I do understand your reply and am aware of the potential causes of interference, it is unfathomable that the speed and performance would drop so significantly between Tuesday night and Wednesday night with no new devices introduced! 3 mbps ds is just not acceptable when paying for BLAST! 200. The only devices I run on the 2.4 band are those that do not support the 5.0 and they are the minority of what is in use in my home.
There has to be some other cause for the very sudden drop. I imagine I'll be having a Comcast tech come back out and re-test modem. When he was here last, we were getting ds of at least 40-50 mbps and, like I said, nothing has changed.
Let me know if you think of anything else I can test. Thanks.

All of the sudden (starting last night) the 2.4GHz WiFi being broadcast from my router ( Cisco DPC3941T) is EXTREMELY slow. The Xfinity Speed test is showing 3.4 Mbps download and 0.5 upload speeds. Totally unacceptable [feels like dial-up!] I've reset the modem several times and tried it again this morning - same result. The 5.0 GHz broadcast is just as fast as normal but my aging ASUS ROG laptop only supports 2.4 G.
1. What do I do to get the 2.4 G back up to full speed?
2. Referring to my modem model, is this outdated? Should I get an upgraded one and if so, which model?
Thanks for the help.
