I'm experiencing slower speeds on ports that are used for uplinking on my RV180:
- when plugging my laptop directly into the RV180 that is used as WAN router, I have nice wanspeeds of ca. 98 mbps
- when plugging into the SF302-08P 8-Port switch that is uplinked to the RV180, the maximum speed drops to 25/30 mbps
- same symptoms for a small d-link switch: when plugging into the switch 25/30 mbps, when plugging its uplink directly in my laptop, I get 95-100 mbps.
I've gone through the configurations, but don't know what could be the issue.
Note that the device reports it's negotiated speed/duplex. Also, i've experienced multiple scenarios wherein 1G when connected to 100M goes haywire. One of our fixes is to hardcode botht he speed and duplex on BOTH 1G port and 100M port, but in your case, you cannot hardcode the settign in 100M since it is unmanaged
Im positive it's the port negotiation of the switch you have, considering it's an unmanaged switch (and a cheap one) :P
Is status>port statistics the only way to check port speeds? --Yes
PS: Do you have any other switch there that supports 1G? How about trying another port on the RV?
