"Enhanced CAT5" = CAT5e, so yes they will work at gigabit speeds. CAT5 and CAT5e both go up to 1000 Mbps @ 100 Hz. "Enhanced" just means it is designed to reduce crosstalk vs regular CAT5.
incorrect source So some articles on internet are wrong when say about CAT 5 being slower than CAT 5e ? the former was about 100 Mbps Megabit and the latter was 1000 Mbps Gigabit on these places. Could you show me some specifications texts ?
The argument you base at would be: "Even so, many installed channels may meet Cat5e performance requirements (with a handwave)."? handwave would mean superficially explained ? and the graphs too: They are Frequency graphs? How could I relate them to speed in bits/s ? My place was reformed in 1998, the cabling are CAT5 (checked a week ago). There are even some inapropriate construct like eletrical wiring passing through same ethernet 'wall hub' in one of the rooms. But I guess this is not from the original reform. It's was afterwards offhand. I am planning to open a pipe in the wall to pass this eletrical wiring away from the ethernet wall hub. How about the lenght, should be 20 cm away?
