Re: XB6 Modem Settings/Requests/Firmware Discussion

@Don_Ca,
Are you now also getting the "Failure! Please check your inputs" error? They completely broke this router.

I can confirm I cannot reserve IP addresses now with my firmware upgrade.

 


... and I  definitely CAN reserve IP addresses.

 

My gateway firmware was updated recently as is now shown as:

 

eMTA & DOCSIS Software Version:Prod_19.3_d31 & Prod_19.3
Software Image Name:CGM4140COM_4.4p8s1_PROD_sey
Advanced Services:CGM4140COM
Packet Cable:2.0

 

I have added a reserved address and it shows up in the device list as shown here:

 

  

Host Name DHCP/Reserved IPRSSI Level Connection    
BigDrive

Reserved IP

NAEthernet 

 

NOTE that this an ethernet-connected device, not wifi, so I cannot speak about any problems reserving IPs on WIFI devices.

 

This particular device, by the way, is not connected DIRECTLY to the gateway.

 

I have reconfigured my system slightly from that described in previous posts.

 

The Rogers gateway is providing the WIFI while my own old Linksys router has now been put in "bridge" mode, and acts as an access point.  So the Linksys uses one of the gateway's hard ports, and 4 hard-wire devices use the 4 Linksys ports.  All 4 of these devices are seen by the Rogers gateway as being part of ITS network, and are also seen as being "ethernet hard-wired". 

And ONE of those is the device with the reserved IP. 

 

This works just as seamlessly as it did when the Linksys was the "router" before Rogers IGNITE.

@ColdGranite,
If you look at your firmware version, it's actually older than the one I and @Don_Ca have. This "newer" firmware that we have has IP reservation broken and fails everytime you try to do it. I also have a similar setup to you that worked when I had the same older firmware version as you.

It is the Inputs error, no matter which way I do it. Not really an issue for me, I use static addresses for anything that I want to have a static address.

Re: XB6 Modem Settings/Requests/Firmware Discussion

Anyone having issues with OFDM? My modem has been using QAM instead of OFDM for downstream. This has been going on for a few weeks now, I don't know if this is firmware related or an area issue. My house is FTTH/RFoG so signal levels are always perfect. 

 

eMTA & DOCSIS Software Version:Prod_19.3_d31 & Prod_19.3
Software Image Name:CGM4140COM_4.4p8s1_PROD_sey
Advanced Services:CGM4140COM
Packet Cable:2.0

@Don_Ca,
How are you setting static IPs for the devices that need it? I have been trying to do that from XB6 and reserving it that way but now that's broken.

Re: XB6 Modem Settings/Requests/Firmware Discussion

I set the DHCP range on the XB6 so that it only gives out IP addresses in a smaller range (i.e .100-. 200 in a 192.168.1.x network) and use the first 99 for static.  I then set the addresses on the devices themselves using IP addresses in the first .99.   So my main computer has a static IP, my printer's have a static IP, my managed switch, etc.  Making sure you are not using the whole range of IP addresses for DHCP is important so that you do not overlap and get duplicates.

There seems to be an interesting quirk with the XB6 in that:

... if you try to set a "reserved IP" on a device directly from the device list in the XB6, then that IP address has to be WITHIN the DHCP range that you set.... even though you are specifying "reserved" and not DHCP.

 

Yet when you set the static IP via the device itself as you describe, then the IP address can be outside the DHCP range of addresses... and the XB6 DOES recognize it and continues to provide access to the device.

Re: XB6 Modem Settings/Requests/Firmware Discussion

Using my Linksys router in "bridge mode" to act as an access point for 3 hardwired devices.  All works fine.

 

BUT... just noticed an interesting feature:

 

With 3 devices plugged into the Linksys...

 

... it does not seem to matter whether I plug the Rogers XB6 gateway  into the Linksys OUTPUT port (as I would expect is normally required).... or plug it into the remaining 4th device port (which I would have expected to be an error).   

 

No matter which way it is plugged in, the other 3 connected devices STILL get their IP address assigned by the gateway and get access to the gateway and to the world.

That's actually to be expected.  When you enable Bridge Mode, all of your router's network interfaces get bridged together to form a single logical network.
