I switched over to the 3100 router after a few years on the Quantum g1100. Coverage is slightly better but I still have a couple of rooms with spotty 5G coverage at one end of the house. I see Verizon has a 3200 extender, but it costs $200. I still have the 1100. I have a bunch of coax running all over the place from when I had FIOS tv, but I stream now. Can I configure the 1100 as an extender to the 3100? Can I connect the 1100 back to the 3100 using the coax cable already sitting there? If so, has anyone seen detailed instructions on how to do this? Are there any drawbacks to this approach such that I should just cough up the $200 and use the 3200? Thanks for any help.
