Hello,

If there is another post regarding this, please point me in the right direction. I can't figure out how to ask the question in one sentence.

I have 2 routers, XFINITY CGM4140COM and a Nighthawk AX8. This has created two different network. Normally I would bridge the xfinity router but my wife's work laptop is password blocked so I can't update the drivers to see the new AX8. So here is the problem, I want to be able to switch the wired PC from the xfinity router network to the nighthawk one. My gaming laptop is connected wirelessly to the nighthawk network as I seem to get way better performance. To access the files on the PC though, I have to switch to the xfinity netwrok. Is there a way to access the files on the PC from any network? If not, how do I switch with network the PC is on?

I hope that makes sense.

Thanks for any help!

I think I am missing something in my understanding of your network configuration.

Does the following link show your Xfinity device (i.e., the XB6 Wireless Gateway)?

Nighthawk router:

One router is all that should be needed. A two router environment is not a usual requirement for most home networks. Often problematic with respect to initial configuration and subsequent management.

How are devices currently connected?

My interpretation of your post:

ISP --- coax -- >Xfinity Router[LAN1] ---> Ethernet to Wired PC] and [LAN2]---Ethernet ---->[WAN] Nighthawk Router

then

Nighthawk Router ~~~ wireless ~~~>Gaming laptop and [LAN] ---Ethernet cable --->Wife's Laptop

Nighthawk router having 1 WAN port and 5 LAN ports.

My overall thought is to just disable all router functions on the Xfinity router (making it solely the modem) and move all routing functions (wired and wireless) to the Nighthawk router.
 
A highly common issue, people add routers and suddenly you are running 2 subnets. Home equipment are not able to deal with >1 subnets, if u want them to be able to talk to each other that is.

Easy fix, reconfigure one of your router as a simple Access Point like THIS. The router that's directly wired to modem should remain as-is.

First, thanks for the reply!

Second, The first link no, the second one yes. Here is the Xfinity: https://arstechnica.com/information-technology/2018/10/comcast-gigabit-cable-available-to-nearly-58-million-homes-and-businesses/

I want to bridge it, but I can't until my wifes work allows her to update the wireless drivers so the can see the Nighthawk. Been a pain dealing with them. Until then, I was hoping to find a way to acces the files using the Nighthawk network.

Ok I will give that a shot. The Xfinity modem/router is connext to the outside cable then a cat 5 is tan to Nighthawk. Will that affect anything? Thanks for all the help!
