I have a desktop playing the role of a server, which is always on and runs Windows 7 Ultimate. Internet connection sharing runs here to give internet access to all the computers in the house. It has a Gbit net port. There is a gigabit unmanaged switch connecting a desktop PC with Windows 7 Ultimate (Gbit net port), a laptop with Windows 7 Ultimate connected via a wireless (N) access point. Finally connected with the switch is a media player (neoTV 550) with a 100 Mbps net port.
All was fine with XP on the server. Since the Windows 7 Upgrade I got better bandwidth in file transfers touching 90 KBs. But I have 2 problems
Windows Explorer: clicking on a shared drive, there might be a waiting time of a few seconds. After that all is very fast for many hours or days until it happens again. This happens once in a while. It could be once per day or once per week with no apparent pattern.
The neoTV 550 does not connect with the shared drives anymore. It connects correctly with the network. It gets the IP address and all. It connects to the internet but not to the shared drives. Then after a few minutes or hours, sometimes days, the connection comes back and all works perfectly. Even if all other computers can connect to the shared drives without any problem.
Cables are all quality CAT7.
What I have already tried:
- delete ARP cache
- autotuning disabled
- Removed RDC (Remote Differential Compression)
- Removed IPv6
- Autonegotiation set to 1000 Mbps full duplex (not automatic).
