How to change the channel on my dir-600

SOURCE: D Link DIR-300 - Connection was Reset - Unable to set up router

Things to try:

1. Swapping the router from mixed mode to G only.

2. Raise up the wireless router higher in the room.

3. Move the router closer to the ps3 or the ps3 closer to it.

4. Run ethernet cable to the ps3 from the router. (clunky but 1ms ping times to the router does make seem worth it.)

5. Put the ole warhorse of a linksys back in and hope for store credit on the dlink. As it seems to have been working for you.

To answer your question:

Currently most things have built in G class wireless antennas. As such they prefer G and the N router eats into the G's spectrum. Not bad but some bleeding of channels is just going to happen and as such N class things will love the N router but the G class have to suffer a bit.

If you have a space where you insert the port number it wont work to save your settings

For setup, you need an Ethernet cable connection to the router, WLAN needs to be configured first before you can use it to administrate the router.
Quick installation guide is here: ftp://ftp.dlink.de/dir/dir-600/documentation/DIR-600_revb_qig_multi.pdf
The default user name is "admin" with empty password.
If you suspect the settings are not at factory defaults, press the reset button at the rear for 20 seconds with the router powered on.
