It’s 2.4 and 5GhZ and picks the channel for me. I already have a box of Cat 5 left over from another job. The best solution so far is to check the auto negotiate on the cards. If I can force 100mbs that will be a good thing even if it has collisions. All I have to do is figure out how to do that.
If you have a 100 foot of cat 5 laying around you can obviously do the ends. Google cross over Ethernet cable. Terminate like that. Will run at the network cards native speed. 1000 or 100 vs the 10 you are getting. (Like moving the fence to let the dog out)
Or.... pull the drive from the source computer and go plug it into the other computer and do the copy at SATA speeds which start out at 1.5 Gbit/s and go up. (Putting a leash on the dog)
Or move the computers like I said and the router and go card to router to card and you will be happy. (making your wife walk the dog)
(USB drive “sneakernet” option is having a well trained dog that walks its self)
