Scenario. I'm in Tbilisi, Georgia. I have very high ping to EU servers(100ms+) plus a huge buffer bloating problem, this test gave me the F rank: https://www.waveform.com/tools/bufferbloat I use an optical Fiber connection, 100 Mbps connection from Magti ISP and fiber connection PC <-> Router.
I can't solve the high ping issue, but I can solve the Buffer Bloating.
I have a router or modem from the ISP. The router is locked and I can access it only with help of the ISP support. No login details at all. The ISP router model name is unknown. There is no S/N or vendor name at all.
I found that UISP EdgeRouter X has SQM support so it can manage the buffer bloating. But this router doesn't have the Fiber input as far as I know.
The question is. If I will buy the UISP router, then connect it to the original router from the ISP, and set up the SQM, will I solve the Buffer Bloating issue or I will face new problems + the same issues + some latencies?
p.s. I'm a complete newbie here, please don't be harsh :>
