I was blaming my computer, loaded with 7gb ram and a dual core processor (not superfast, but adequate) on problems.

Today, I found out it was the switch that is underpowered.

The network started with a D-link wireless router with 4 ports. 3 lan cable runs directly to the server and two terminals. One goes to a switch, and branch out to 3 more computers. One of the computers has been running quite slow.....

The I added a 50 ft lan cable to another terminal. This essentially killed the switch, and crashed it.

So I replaced the whole set up with a new wireless router with 8 ports. Now all the computers happily link up directly to the router.

Then I noticed that the computer noted above, now run much faster!!! The bottom line is that an under-powered switch over loaded by long lan cables burn itself out, or becomes a bottle neck. A router with multiple ports is better powered, and can handle longer cables better. I guess it would also help if I didn't buy those cheap $10 switches, which is likely under powered.

Has any one have recommendations for routers, switches, and wi-fi set ups to maximize efficiency of AC?
