Re: Anybody with Ethernet knowledge?
Well anyway, is there some simple way how to measure packetloss from unmanaged switch to slightly-managed NAS to reliably discover whether it works after it succeeds in negotiating GbE?Less jewellery, more gold into electrotech industry!

Re: Anybody with Ethernet knowledge?
put a pc on the switch and ping the nas?Comment

Re: Anybody with Ethernet knowledge?
If you get another PC on that network in addition to pinging you could try a packet analyzer like Wireshark.Comment

Re: Anybody with Ethernet knowledge?
Pinging was OK but these packets are sometimes able to go through where TCP/IP are not - I have seen that. So that may not be so telling.Less jewellery, more gold into electrotech industry! Half of the computer problems is caused by bad contacts

Re: Anybody with Ethernet knowledge?
Correcting the older slow Ethernet standards:
10 base 2 and 10 base 5: requires 1 wire plus shield (2 conductors, half duplex by definition)
10 base T: requires 2 twisted pairs (4 wires, duplexing by protocol, but 1 rx and 1 tx pair)
Remember that 10baseT also required crossovers to connect two computers together without a hub/switch, granted modern machines did auto II/X negotiation.Comment

Re: Anybody with Ethernet knowledge?
Crossover works even now, it should be used between two computers but as most of them can do auto negotiation, it is not needed. But it's safer, auto does not always work.Less jewellery, more gold into electrotech industry! Half of the computer problems is caused by bad contacts

i need help getting all this nonsense working in unison
please adviseComment

Re: Anybody with Ethernet knowledge?
I'm assuming (sometimes dangerous) that you want all the machines to be on the same network. If that is the case, it might be a better solution to only have one router assigning the addresses and opt for changing the other routers to act as switches. This would entail turning off DHCP in all the routers except the initial one, at the network source.Comment

Re: Anybody with Ethernet knowledge?
DHCP and NAT, than you can use all 5 connectors. If you leave NAT than you can only use those four which are switching.Less jewellery, more gold into electrotech industry! Half of the computer problems is caused by bad contacts

Hi guys, I need your help again.
I have this iMac from a customer that shut down during a storm along with all the other devices in the house. In particular, the router, connected via Ethernet to the iMac, caught fire.
When I removed the screen from the iMac to check the status of the LEDs, I noticed that none of them were lit. I had a perfectly compatible and working power supply, so I tried it right away, but the problem remained the same (no LEDs). With the thermal camera, I noticed only a slight warming (32 degrees) of the NCP1605BG chip on the power supply. The rest was completely... -
I have Avaya 9641G IP Phone wich reports "No Ethernet" on the screen during initial start. I have intention to trace an Ehternet signal from the very input RJ45 jack throuth the phone mptherboard to the Broadcom communication CPU input pin.
Need youe advice how to: first I have suggested to buy an oscilscope, but not sure what to select, the pro version may become too expencive, and basic version may not capture high frequesncy signal. I really don't what to spend a fortune just for the pleasure to see the Ethernet frames. I also considered to measure just an AC voltage at the... -
I've got a Xbox 360 Elite with a Jasper V1 or V2 PCB as far as I know. 150W PSU and rated for 12.1A and the Xbox has the MFD 2009-10-14
Issue is that there was a lightning outside and now the ethernet does not work. Power cord was unplugged. Only ethernet cable was plugged in. The router and some other stuff died.
No error codes. Xbox seems to work as I should. When i plug the ethernet cable in nothing happens. Dashboard only tells me to plug in a ethernet cable. Or i don't remember.. if Ethernwr maybe was greyed out since it didn't recognize a connection.
