Hello. I am sorry to bug you here, but my family has been having a fairly common issue. We were told a while ago that changing from a 200mb/s to a 1GB/s plan would fix an issue where a device farther from the old modem would be able to reliably play video games. Now that I am back from college, however, while on the 2.4ghz signal with all five bars, I often experience an unstable internet signal, ranging from a nice 350mb/s download to a more common 20mb/s. I am mostly the only one with a device that's hungry for our internet thanks to streaming, gaming, and Zoom, so there are no signals blocking it. There are also about two walls or so in the way, but once again, the new plan and the five consistent bars were supposed to 'fix' the issue since the router is in the most ideal position and should be a lot stronger, which on paper, it is. Furthermore, an ethernet cable is not possible due to the time when the house was made.
Now when I called the support, I was dismissed with the idea that since the ethernet reliably gave me my speeds instead of the Wi-Fi at any location in the house (500-600mb/s vs the supposed 1G). I pushed that we were told that this new, 'cheaper' plan (which is not true in the long-run) was supposed to fix my issue, and I was only upselled with 3 xFi pods at a high price that's out of our already stretched budget thanks to Covid-19. This type of treatment raises a question now. How do we fix this issue that won't require us to throw more money at it and hope that we're being told the right answer when the previous worker was incorrect?
