Re: New XB7 Gateway

I have the XB-7, Blast, etc. Wired I'm pulling ~300Mbps. WiFi from 20' away about 70Mbps.

 

Comcast / Xfinity, just retired after 40 years as a Network Administrator with years at four Fortune-500 Corporations so I know a *bit* about networking. Any input greatly appreciated but please spare me the basics.

 

Thanks.

Re: New XB7 Gateway

Since you’re getting good on Ethernet and not WiFi, I would check the following first:

1. Are the bandwidth settings set to the highest possible?

2.4 GHz should show as 20/40 on the settings screen

5 GHz should show at least 20/40/80 or even 20/40/80/160 as the selected option.

2. Are you only using one SSID at this time? If so, try it with them being separate.

3. What kind of device are you testing with?

Re: New XB7 Gateway

Thank you for the quick reply!

 

Testing with a reliable known good laptop that is giving me the ~300Mbps (avg ~245Mbps) hardwired throughput.

 

Re 2.4 and 5GHz settings - not an option I am seeing within the GUI for the XB-7. 802.11N Channel Width in Win-10 Pro for WiFi set to 20MHz for 2.4GHz. For 5GHz, set to Auto.

 

Only one SSID in use.

 

Again, many thanks.

Re: New XB7 Gateway

Gateway > Connection > WiFi

Nothing there?

I would definitely try splitting the SSID for a test. What I think could possibly be happening right now is for some reason your device is probably latching onto 2.4 GHz for some reason. You’re probably not going to be able to get that full 300 because of 802.11 N. My XB6, personally, when on an 802.11 N only device on 5 GHz maxes at about 150 Mbps. While my AC clients can get much higher.

Re: New XB7 Gateway

Thanks. The only issue is this is relatively new behavior. E.g., two weeks ago I was pulling ~145Mbps but the laptop may have been connected to the Extender (Netgear EX7000, AC1900) which this laptop will latch onto when it's up. I'll try it and get back to you.

 

Channel Bandwith for 2GHz is 20/40. 5GHz is 20/40/80. My bad on not noticing that before.

 

Best,

Re: New XB7 Gateway

When it is directly connected to the gateway over its WiFi, sometimes the Connected Devices could also tell you which frequency it’s on. It’s better to do the SSID split as that will be the better test.

Re: New XB7 Gateway

Here's a good one from ComcastCares Support on Twitter. I asked where the Antenna's were on the XB7. I.e., side, top, back, front, rear. Enjoy.

Should I change the 5GHZ from it's current 20/40/80 to 20/40/80/160?

Re: New XB7 Gateway

Those settings are locked to you, thanks to xFi Mesh Mode so you wouldn’t be able to change it to that anyhow.

From my knowledge at the moment, the XB7 does not support 160 MHz (same for XB6) nor does it support 802.11 ax at this time

I was able to check if the XB7 was available in my market (Huntington, WV) with customer service. It was and was shipped out to me on Friday. I should have it on Wednesday to swap out for my XB6.

@Wardman Go to 10.0.0.1 and use the default login "admin" and password "password" or whatever you changed it to. Sign in, then go under "Software" and you'll see the version. The one listed here is for an XB6 not an XB7

Re: New XB7 Gateway

I'm seeing this, so think it is current.  Agree?:

System Software Version

eMTA & DOCSIS Software Version: Prod_19.2_d31 & Prod_19.2
Software Image Name: CGM4331COM_3.14p9s1_PROD_sey
Advanced Services: CGM4331COM
Packet Cable: 2.0
 
Still unable to connect to my HP M1217nfw using WPS though.  It says conneted, but never actually does.  Works fine with USB.  I've disconnected that too to see if it was having problems with some sort of handshake (never did with XB6)

Re: New XB7 Gateway

I haven't had much luck with WPS. I'd recommend trying to use the on-printer screen first, and as last resort the HP software and connect wirelessly.

 

Good luck with not getting a ton of bloat installed, triple check the opt-outs, they are embedded as links in the text as you go through the installer.

As an FYI, WPS has a security vulnerability. You can Google for more info. Never use it. Disable it and always configure your WiFi settings manually !

I just got an XB7 with the 600 Mbps plan, and what you describe here is exactly the issue that I am having.  A direct connection with laptop gives me ~345 Mbps.  When I switch the XB7 to bridge mode and use my own firewall I get ~400 MBps. I am also seeing articles related to this device, and calling out the Intel Chipset as the issue.  Are other folks seeing this issue?  I am hearing that anything over ~400 Mbps and this device starts choking.

Re: New XB7 Gateway

Just did a search and was able to confirm that this model is using Broadcom and not Intel.  Still getting poor throughput.  Comcast even provisioned the modem for GIG and it could not push more than 400 Mbps through it.

Re: New XB7 Gateway

Just ran speed test.  Hard wired - 694MB download  Wifi through a Plume pod - 100MB download.

 

Still wish the pods had a way to force  a connection to them, meaning my laptop is 10 feet from XB7 and it takes a while to learn it is a better conection point when going to wifi.  Oh my, we used to have 56kbs dial up 🙂

yeah, this is either a bad unit, or there is some issue locally.  Even after provisioing it for GIG speed I could only get 400 Mbps

Re: New XB7 Gateway

Go to Xfinity xFi
Go to Network (3 Signal Bars Icon)
Click Pencil icon on top right
Check use 2 different wifi names for 2.4 and 5
Type in the fields for your names and passwords for 2.4 and 5.
That works.
Then check 10.0.0.1
Go to connection then wifi and the changed also applied there.
Go to your device wifi and you will see both that you set up and can connect.

Re: New XB7 Gateway

 

What is the success level with Xfi Pods and the XB7? I picked up one 6/9 and attempted install 3 times over the following weekend. Each time I would add any pods the overall system speed would decrease to ~1mb up and down (even at the gateway). I ran out of of time and went back to the XB6 and all is fine other than issues I have always had. I was hoping the XB7 would fix some things. I did note that the firmware updated and it rebooted after install and then I had WiFi6/802,11ax capability. It was around that time that I started having issues with the total system and pods. I think wired Ethernet was fine the entire time? I found a couple other folks that have received defective units so I thought I would ask. If there is yet another newer firmware out then I might try it again but I probably need to try an entire new unit? And maybe that would be a better use of my time? I've been unsussessful to get this issue escalated and I was busy and on vacation before now. The thought of having to go back to the store, again, and swap is not desirable. Guess I will try next week when I will be near one.

With pods you have to have the SSID the same for both 2.4 an 5 so in my case and issues that would fix the problem but it would also diable my pods. At least that is how it is with the XB6. I can't make the XB6 do that unless I remove all my pods and that is now not an option as I use the Ethernet port on one to run my solar monitoring as my old power line Ethernet devices gave up the ghost (or at least wore out or there is some new line interfearence that dosn't allow them to reach that far anymore?)

@ComcastJonathan Please see my post about issues with pods killing the XB7. I'm wondering what the failure rate has been with the XB7 and it sounds like I really should get it swapped out? Has there been any newer firmware released since Early June (spcifically since June 13th-14th?)
