I've found many secured networks to get hammered with low speeds. Fixes are all over the map so I'll wait to read what isn't stock here.
I'm having huge internet download speed issues. I pay my ISP for 75-100Mb/s. I have 2 XB1's. One wired and 1 on wifi. They only download at 10Mb/s or less. They are the only devices on the secured network. I thought my Arris Surfboard modem may have been causing the issue, so I rented a different modem from my ISP today. Still having same issue. Tried a different brand router, speed got better for 5min, then the issue came back. I tried my Arris modem straight to a computer and got 134Mb/s for about 5 min, then back to below 10. I have a tech coming out Saturday, but this is bs. Any help is appreciated.
