I just got the WNDR4500 and set it up yesterday. Everything works great except one annoying issue: I have one PC that keeps getting limited connectivity and i have to release/renew the ip to fix it (or power cycle the switch). This happens after 3-5 min. The other devices stay connected even though they are after the switch.
I have my network set up as follows: Cable modem connecting to the router. Router wired connection to PC1, Network Printer. I have a wired connection from the router to a switch in my living room. From the switch there are wired connections to PC2(the one with the limited connectivity issues), a network storage, and PS3.
Everything stays connected, even the PS3 and the network storage, except for PC2. PC2 drops from the internet and the LAN, and the Netgear no longer sees it as a connected device until I release/renew on the PC.
With my old Asus router everything works, with the same PC and the same switch so the issue is with the router. The new router is gigabit, so not sure if that's part of the issue. I'm using a combo of Cat5/5e so maybe switching to cat6 will help?
I tried setting a static IP for PC2, and DCHP. That did not make a difference.
I tried leaving the router with everything defualt, and upgrading to the latest firmware.
I also tried uninstalling the network card on PC2 and re-installing, although I did not check if there was an upgrade to the NIC.
