Global Cache GC-100 and gigabit network

Post by abl »

Since a few weeks I have a Global Cache GC-100, with the intention to get it up and running in my homeseer system.
I had some problems with connecting it via my gigabit switch. When I connect via a direct link to a pc (crosscable) it functions flawlessly, but as soon as I put a switch inbetween, I encounter instability.
Now I thought that an option could be to add a secondary network card to my homeseer server and have it directly connected (next to my homeseer server being included in the gigabit network). Do you think there is a chance of succeeding? And could I add a second network card via pci or via usb? Can this also be in the same ip-range?

is there an answer from the vendor for your problem, on the website is see pictures of a gc-100 attached to a router. is it a switch or a hub ? a cisco switch is to be programmed.
you could also try to use beteen the gigabit switch and global cache the old 100mb switch or 10mb switch , the global cache is 10 mb ethernet side so maybe that is the problem ?

The vendor has been very responsive (lots of e-mail) and testing programs. But they keep saying that the problem is related to my gigabit switch (even if I put a 10/100 mbit switch inbetween). My gigabit switch is unmanaged (checked D-Link support).

I had a similar case once; adding a 100mb switch/hub in between helped me too to get rid of the network problems; and it's easy to try. The gbit switch was also a D-Link.

1 i assume you also hava router for the internet, and if you putglobal directly in the router next to the switch. helped me with proliphix.
2 try another switch see if indeed the switch is the problem, eg your old one.

I tried both solutions. I have a 4-port router, one port is connected to the gigabit switch. I tried connecting the GC-100 to one of the three ports directly as well via a switch. I also tried to use another 10/100 mbit switch, but the problems remained. Could it be that the switches should both be D-Link's? Or should I try to have a secondary network card in my Homeseer server?

so another switch gives the same problem as the gigabit one. then i don't understand the vendor says the gigabit switch is the problem.
the web interface of the apparatus dhcp or fixed ip adres, problems with 255.255.255.0 settings ? another network range.
the problem if two switches dont work is probably a network problem.

you als could ask on gathering.tweakers.net in te network section , all kind of network nerds can read the problem.


of course you could by another network card to put in the computer, but you could als try to find why this isnt working.

isnt there a global user forum ?

Sometimes it functions in a single pc - 10/100 mbit switch - gc100 setup. But it doesn't function flawlessly. As soon as I integrate this 10/100 mbit switch into my gigabit network, it only works once, and after that the software hangs (and the GC-100 gets unpingable). The only way it works is via a direct link to an old pc via a crossovercable.
I tried several fora and contacted DLink, but they just state that it is an unmanaged switch so they can't do anything about it. The helpdesk of GC-100 is great but they say that if it works within a crossover setting, the GC-100 functions and it should be a network issue. I have my doubts there as I have almost 20 things hooked up to my gigabit router and all is working great, except the GC-100...

this kind of problems is for me a reason not to buy globel cache products. i have had it with products using ip/tcp and not functioning good an lokal networks or the internet network
take rfxcom and proliphix it functions lokal and on the www without problem that is the way it should be.

I haven't read the details of your problem but there's one thing I would like to mention.

Duplex and speed differences can cause extremely weird or inconsistent behavior.

Try to program your switch to match the speed of your GC device and FULL duplex.
