Fluctuating Speeds

Hello,

 

I am a business customer in White Marsh (Rosedale), Maryland.

 

Usually when I get slow speeds I will reboot the router and modem and the rated speeds will come back.  However, whenever I start using the bandwidth for streaming, uploading or downloading the speeds may fluctuate.  Here are my modem stats. Please check to make sure it is normal.  Thanks

Hello WoNGeR007 and welcome,

 

Please make sure that your login yo you Comcast Modem (CG) using 10.1.10.1 and username=cusadmin, password=highspeed click LAN and make sure  Leasetime=FOREVER and DNSs are programmed to Pri=75.75.75.75 and Sec=75.75.76.76. If this still does not fix your interconnectivity drops issuem call 18003913000 and ask agent to make sure your CG WAN segment DNSs are programmed as specified above.

 

Hope this helps you out.
