My home network is set up properly and I happily have 2 Windows XP laptops and one 1 Windows 7 desktop connected to the internet. I bought a Lenovo Y450 (Vista) this summer but I haven't been able to use it because it causes my entire network to stutter. I'll have internet connectivity for around a minute before it drops for a couple of seconds before reconnecting. Keep in mind this happens to not just the Lenovo Y450 but to all the computers connected to the network. I'm pretty sure I've had guests stay at my house who used other Windows Vista laptops on my network without it crashing every minute.
My basic set up:
Connection from ISP goes through a Buffalo BBR4MG before it gets split up by a CentreCOM FS716TXL where the wires run directly to various LAN sockets around the house. This is pretty much the standard set up in all modern houses in Tokyo.
I'm going to try bringing the laptop to my school tomorrow to see if it works with their network. Hopefully I won't crash my entire school's network. Please help me diagnose and fix my problem.
