I'm still having this issue. A networking guy told me that framing |
39 |
errors can typically come when the two ends of the connection (card and |
40 |
switch) are not set to the same parameters such as half-duplex vs. |
41 |
full-duplex. He suggested I try forcing both ends to be the same and |
42 |
see if the errors go away. |
43 |
|
44 |
However this is just a cheap 8 port TrendNet switch that doesn't have |
45 |
any management capability. Thus I thought I'd try forcing the NIC to |
46 |
one way or the other and see if the errors are resolved. I've Googled |
47 |
for information on how to (a) find out the current setting and (b) |
48 |
change the setting but have been unsuccessful. Can any one point me in |
49 |
the right direction? |
