Converge keeps refusing to upgrade my old ZTE router

Hi Everyone,

I was told by a few technicians before that my unstable wifi signals might be caused by old ZTE router which was installed way back when i first got their service. The last technician who came 2 years ago told me that i should be due to get at least the newer samsung routers.

I've requested this several times over many years but i keep getting the same "New routers are on hold or out of stock" first with the previous samsung model and now with the new wifi 6 routers that they're advertising with their service.

Does anyone have suggestions on how i can successfully request for one of the newer models without having to go through customer service?

Thanks,
