i've got a hr23 that i'm having all sorts of network issues with. here's a link to my previous thread... http://www.dbstalk.com/showthread.php?t=191844 anyway, now i've got the hr23 basically shutting down my network. i have a linksys wrt54gl that runs into a zonet 16 port switch, and everything on my network is wired into that switch (including my hr20 and hr23). i used to have a linksys sr224 switch, but i replaced that with the zonet because i thought the 224 had failed. nothing on my network that was plugged into the switch would operate, so i ordered the zonet to replace it. well, tonight i was watching something on the hr20 from the hr23. all of a sudden, i get a message that the receiver has been disconnected from the network. also, all my computers lose connectivity. i think to myself, there's no way this switch went bad this soon after the old one did (it's only been connected less than 24 hours)...so, i go downstairs and look at the switch - all the lights are blinking rapidly. so i start disconnecting things...the hr23 happens to be port 1 on the switch. as soon as i disconnect the hr23, the lights stop blinking. i come upstairs and check my computers...they're all connected with internet again. so, i'm guessing the hr23 must have a bad ethernet port, or something of the sort that is flooding my network occasionally. here's the kicker...i reset the hr23 via the red reset button and re-ran network setup on both boxes, and i have whole home and everything working again AND i have connectivity on my computers. how should i go about fixing this? it's obviously the hr23 causing the issues, since they stopped immediately after i unplugged the hr23 from the network...i want to add a third (and maybe a fourth) hd dvr, but i was going to go out and buy a hr24 to make sure i get one of those...should i try to replace the hr23 and ask for a credit to buy a hr24? will directv even replace the box on account of the network port going bad? for that matter, has anyone ever seen anything like this before?
