Manual IP Issue With the New XB7 Router?

The new Xb7 has well documented issues with slightly older printers, they don't work on the XB7 wirelessly, you can see some of the threads I linked about this issue below the images. The Xb6 router works just fine though before we upgraded, and people end up having to switch back to the Xb6. My printer is 7 years old, it should be compatible.

So I went into the XB7 gateway (10.0.0.1), separated the 2.4 and 5ghz bands, then disabled the 5ghz band. Reset the printer and gateway, Connected the printer to the 2.4 ghz band only.... Still having an IP conflict issue. Epson WF-845. The printer is able to find and connect to the network, and shows up as a connected device in the Xb7 gateway, but it has an IP conflict issue. Its unable to communicate, not useable, cant print.

I then changed the Epson printer from DHCP to Reserved IP within the XB7 gateway, and made it 10.0.0.212 Then went into my printer software and manually set the same IP. Still does not work. Any ideas? Is the gateway info wrong? Any ideas?

Have you tried setting the printer to "Acquire Automatically"? That's how I have my "Reserved IP" devices set up.

odd i just posted a reply but it don't show up, after looking at your screenshots again, i see a problem, on your printer select obtain a Ip  address automatically, don't try to set a static IP

@PcSteve I'm having the same exact issue as you.  The only difference is I have an epson wf545.    I've tried pretty much everything you've tried except doing a factory reset on my xb7 and then setting everything up manually.  I used the xfi app and did the automatic transfer but just can't seem to figure out what got cached as everything else connected flawlessly.  I found others that have this issue have went back to xb6.

So check your firewall settings, if it’s on Maximum Security, it blocks lan traffic, so I just verified this, change to a lower or custom setting, printed right away so after some more checking my printer won’t even print on the low security setting which is the default one, so I made a custom one, prints beautifully now

Same issue with me but with the Epson 725. Everything was fine on the XB6 but now the only device in my house that won't connect is this printer. I've tried everything I've seen in the threads about this issue. Hoping someone at Comcast can find the solution. Yeah, my printer is old, but its still running on a 802.11g band and even without a password, it won't connect. Hardwired ethernet and USB work fine. Hoping we can find a solution.

Some epson printers will only connect on certain channels, my epson printer is roughly 11 years old, works flawlessly with my Xb7, are you by any chance trying to set a manual ip?

I tried a manual ip and automatic ip. I did get it to connect to the network with a 192.168.0.xxx ip.  But the gateway on the printer was 0.0.0.0. The printer said it was connected to the network but the computer could not see it. The second I changed the gateway ip to the default 10.0.0.1 on the printer, it fails. Also my DHCP lease is 10.0.0.2 - 10.0.0.243. Not sure why the 192 ip connected somewhat. Possible lead

 Did you say the printer works connected Usb and ethernet? Or don't work at all? Also whats your modem/gateway setup?

Printer connects through Ethernet and usb fine. Wireless is the only thing that doesn’t work. Was working on the xb6. 

My modem setup is just the XB7, no pods, no other router. I have Ethernet to a windows 10 PC and Ethernet to a Verizon cell tower booster. All other devices connected through wireless. Wireless is 2.4 and 5 on the same SSID. (I’ve tried splitting them to test the printer on just the 2.4, no luck)

So, i am guessing the the Verizon Booster is probably is on a different subnet,  probably where the 192.168.0 comes into play, So, when you tried to set a manual IP, if it wasn't in the 10.0.0.244 - 10.0.0.254 range absolute fail, according to your dhcp server Ip range, So, printer connecting and printer printing, two different things to me, I ask because my epson connected but failed to print, i was easily able to fix, But if your printer prints using usb and you set it as the network printer, it should print on your devices wireless as well as ethernet  connected devices as long as they are on the same subnet

So the printer prints over usb and Ethernet but I want the printer to be connected through WiFi only. My printer is far from my computer and the usb or Ethernet cord will be in my way. I’m in an older house so no Ethernet plugs on the walls. (I know there’s other solutions like Ethernet over power or MoCa I just want the darn WiFi to work like it did on the xb6).

Ok, fair enough, so when you try to connect via WiFi, does your WiFi ssid show up at some point, where you can put in the correct details? Or does it not show up at all?

It does show up on the printer screen. I select the SSID then fails to connect.

Sorry I am asking so many questions, does it give a error? Or no error? How do you know it doesn’t connect? It can be connected and you still can’t access it
