OBI100 web interface becomes really slow
dhobi:
Support recommended that I switch the port setting to 100Mbps/Full-Duplex which surprisingly is not the default. This seems to have solved the slowdown problem. I'd like to understand why though and whether the problem is with the router port or the OBI device. It would also be interesting to hear why 100/FDX is not the default and why there's no auto-negotiate option.
Just for the benefit of someone who may be running into the same issue and looks at this thread, here's how you enable 100Mbps/Full Duplex:
1. Dial *** 0
2. Enter option 27 and press #
3. Press 1 to set a new value
4. Enter a value of 1 and press #
5. Press 1 to confirm/save
6. Hang up

Glad you finally got it working, although that's exactly what was suggested earlier in this thread ;D

Yeah, thanks for the suggestion, I didn't believe in it until I heard it from multiple sources. Weird problem. Any idea what might be going on?

Hi dhobi,
My gut reaction is it has something to do with an attempted Auto-Negotiation of the link (i.e. 10 or 100, half-duplex or full-duplex). I realize that the default setting from the factory is supposedly 10mbps half-duplex, but I have to wonder if the default setting isn't actually 10mbps half/duplex with auto-neg. If so, then the auto-negotiation is attempting but failing between the OBI and the network device to which it is connected.
Just a theory,

dhobi:
Anyone getting 100/FDX without forcing the setting?
And why 10/half causes the web interface to be so slow is beyond me. The call quality is not affected when that happens, it's just the web interface and only a reboot fixes it.
My OBI has been up for 8 days now and it's behaving normally with 100/FDX. Oh well, the mysteries of hardware and software...
