I recently got an Ethernet cable in the hopes of making my online gaming more responsive, but to my dismay it made little difference in latency measure on the Xbox Series S. It merely dropped from 146ms to 143ms.

I use the modem+router provided by the ISP, a Sagemcom Fast 5655v2. According to preliminary research, the ISP blocks any alterations so I would have to jailbreak the device to explore other solutions. I’m open for suggestions in that regard too! I’d like to know if I can determine if the problem is on the router or the ISP.

On your suggestions please consider that my country’s currency is worth less than one fifth of the US dollar, so I’m not looking for anything even remotely close to the best setup possible, but merely a significant improvement. Anything above 50 US dollars is already too much for me.

So, with that in mind, what do you recommend?
