CM1000 Xfinity issues
I'm getting lag and slow download speed on games
I feel like I'm on the same boat as you guys. I recently updated Xifitnty Gig service and purcashed a CM1100 to handle the new speed, but so far I'm only getting half the speed downstream (500-600mbps) and full upstream speed (40mbps). I've factory reset the modem and Orbi router once, still getting the same issue. Is there a way to check the boot/config file?
I have a tech coming in tomorrow morning to check the line, but i have a feeling the line will not be an issue.
jdmoto , just now seeing this. Netgear suggested I return my modem and get a replacement. This did not NOT result in better speeds.
I believe I ran into kingtj's outcome in another thread. I think he returned his modem, as he was definitively able to get gig speeds with another Comcast modem.
I picked up an xFi and local Comcast store, but it did NOT improve my speeds. In fact, slightly slower than my CM1150v.
I'm not sure what I'm going to do next. How did your tech visit go, and did you find finally attain expected speeds?
- JJNorcal, during the tech visit the tech reloaded the firmware into the cm1100. After the update and reboot I was able to obtain the gig speed. 950/40 but only to certain servers. I'm guess this is due to server limits and distance. My connection to Xfinity servers is gig speed.
I'm sorry to hear that your still having trouble...I have the Netgear CM1150v Docsis 3.1 cable modem telephony and am curious about the downstream channels. Channel 32 is not locked on. Channels 1-31 are locked on, but I do not see any of the Docsis 3.1 frequencies allocated to the modem. I was told the Docsis 3.1 frequencies are above 677Mhz. My frequencies are 477-677. I am experiencing erratic download speeds while the upload speeds are somewhat consistent ranging between 32-41mbps. Downloads range from 647mbps down to 25mbps. Powering the modem, re-provision from xfinity, multiple technician visits, and so on. Any help?
