Blast! Questions

This week I had some issues where my Roku and other devices would not recognize my "in-home" network.  I had my own Netgear CM500V (which is xfinity approved) & google wifi.  Turns out, after 3 hour tech visit, the modem was the culprit.  Currently I have the xfinity supplied router/modem.  

 

My question is, since the modem (now in bridge mode with the google wifi) was replaced my speed went from avg 275-285 mbps to avg 350-360 mbps.  Honestly I don't see a "real time" difference but it is nice for the faster speeds.  Has anyone else experienced this speed increase?  And, the tech said xfinity was doing a "major" update to system which could rendered my modem inoperable, anyone heard this also?  Thanks.

 

And, thanks to all who replied with suggestions earlier this week concerning my issues.

Re: Blast! Questions

The speed you had with your own modem would have been Blast! 250 with overprovision that would be as you say 275/285.

Not sure if you are aware, Comcast have done some free upgrades. Blast! is now 300, which rises to around 360 with overprovision.

I'd be tempted to stick your own device back on and see what you get?

I'd add to the above that the device is still approved for speeds up to 373Mbps, but being a 16x4 channel device, it could be time to look for a new one. It should still work though.

Thanks for replying. Are there any modems you would recommend as an upgrade to the CM500V?

Be sure to check the box for "voice/telephone enabled" if you have voice service. They have recently added a couple of modem/voice devices (eMTA's) the Arris3202 and the Arris2402. These are both Docsis 3.0.

 

Me personally I'd go for the Netgear CM1150V that's a Docsis 3.1 device.

There is an Arris T25, but as far as I know it's not even on sale yet.

I haven't mentioned the devices with built in router, as you have your google device.

 

Scrolling down the page and clicking "show more devices" will reveal your Netgear eMTA. Like I said above, it is still approved for Blast! 300, so I would try that again, just to see what you get directly connected to a computer, leaving the router out.

 

Then again you may not want to mess with it., good luck! Smiley Happy
