There was an ongoing issue with my FiOS before this forum got changed around. The 360 is the ONLY thing that has ANY problems with the network. My PS3 worked fine, all my computers work fine, my Blu Ray Surround sound works fine... it's ONLY the 360. What happens with the 360 is that it either randomly disconnects me and complains about the MTU, or it disconnects me and just doesn't connect again.
Here's all the details from the previous posts
Router/Modem: Actiontec MI424WR
Version of Firmware on the router: 188.8.131.52
The 360 has a WIRED connection
The 360 has a static IP connection, all ports for XBL are forwarded to the 360
Down: 20 MB/s
Up: 5 MB/s
Ping Test Jitter: 1ms
Universal Plug and Play has been disabled.
MTU is set to Automatic on the router.
W: 0000 - 000B
X: 0000 - 000D
Y: 0000 - 0000
Z: 0000 - 0000
ID: 0003 - 0000
The Xbox works fine on ANY other network besides FiOS. The cable that the 360 is hooked up to is perfectly fine, and allows me to connect with my Laptop (which is where I got the speed tests from)
Any help is appreciated because with PSN down and Xbox doing this, I'm about to throw them both out the window.
