2 Gigabit Routers

[Charken]

So far I have manually set the NIC on the HTPC to 1 Gigabit speed and at this stage the it seems to be holding at around 20MB/sec. Which is enough to stream HD content. I'll see how this holds out, although I don't understand why this doesn't simply work at full speed.

Thanks for your comments and help.

Replacing GS105 seemed to help in his case. I don't think you need the GS108T. Just replace the GS105.

Some NICs and switches still have trouble auto-negotiating. Seems you found a case.

HI: My LAN is using daisy chained switches, one Cisco SG200-08, one Dlink DGS 1008D and three Trendnet TEGs59g switches and one DLink 655 router used as a wireless access point and switch (DHCP turned off). These are all gigabit devices and everything seems to be functioning perfectly. Generally switches keep track of where messages need to go by remembering MAC addresses of sources and targets in packet data. There seems to be a 256 Mac address limit to the smaller switches. It does not sound as though you have violated Mac address limits. If any of the switches have routing capabilities, i.e. DHCP or are actually router/switches they should be configured as access points. If too many of your attached devices spend a lot of time talking on the internet they may be overwhelming the main router and switch. Good luck with this. George 5164

I don't know how long this will last as I haven't tested it properly, but will work for some days.

I don't know what happens to drop the speed after some time.

This tells me that your 8 port switch is having erratic behavior. Only when you remove this switch does the problem go away.

Try replacing with a different switch if you have one, and see if that fixes your problem.

Or, conversely, you might be having a problem with the 5 port switch, since you still have the problem a few days later. I would bet money on one of those switches being the problem.
