Older wireless Macs and D-Link wireless N routers Network
I bought a new D-Link DIR-625 router and got it to work with all my computers except one -- an older PowerBook Pismo with an AirPort wireless card. I kept getting the error that it couldn't connect to the airport network. The machine would connect to my old router, and to my neighbor's router, just not my new D-Link router. For days, I tried everything I could find to fix it. I called support multiple times, and tried everything that they suggested. Their suggestions were of no help, however.

I finally stumbled on to the fix myself. I had to change the wireless mode from "B,G and N" to just "B and G," and then it worked fine. The problem is that my new MacBook has N wireless and now can't use my new N router at full speed. I guess that is why it is still called "draft" N router!

Older wireless Macs and D-Link wireless N routers

i don't think older wireless cards are compatible with WPA2 security, which is what 802.11n uses. when you set it to B/G only, it's probably setting the security to WPA.

i would advise you to get a dual-band router (i use a linksys wrt610n) so that all your B/G devices are on 2.4ghz and all your N devices are on 5ghz. then you can have WPA/TKIP running for B/G and WPA2/AES for N.

I had problems getting a "G" Mac and "N" Mac to coexist with a Netgear N router. Really, the problem was that the N Mac would often connect with G, and skip the N connection.

The trick I found was to give the G and N networks different names on the router. I don't know if your DLink router has that possibility, or if it would affect connecting with G. The Netgear allowed me to set the G and N names the same, and supposedly the Macs should try to connect with the best possible method, but this didn't always work.

The only other problem I had was a sudden surge in the number of wireless routers in the neighborhood, and changing the channels on the router fixed the connection problems then.

i don't think the D-Link DIR-625 is a dual-band router. but if you do use a router like the wrt610 that runs both 2.4ghz and 5ghz simultaneously, then yes each SSID should have a unique name.

Unfortunately, the draft N requires all wireless radios on the LAN to be draft N for that higher speed. I've been in the same place with my Wallstreet and DIR-655. My solution was to buy a wireless N pcmcia card. You can find them for sale all over. [link:]http://eshop.macsales.com/item/Edimax/EW7708PN/ OWC sells this one for about $50. I found the same card on sale for $35 somwhere about a year ago. Good luck.

As an additional note I have a DIR-655 with the latest firmware and, although B and G work flawlessly, N does not work (at least with iMacs and Macbooks). It appears to work (succesfully negotiates) but once you actually start using the connection (like copying a big file) it consistently locks up after a few megabytes of traffic.

I've reported this problem to D-Link. I also found some note on the web stating that a very old version of the firmware (1.02 I believe) doesn't have this problem, but that version is no longer available on the D-Link web site.

Actually, I just read kyngchaos's and sfgecko's excellent replies and it reminded me: My latest firmware upgrade allows for a "Guest" connection with it's own password. I think it may allow for just what was suggested. So you might also check to see if there is a new Firmware upgrade available.

I would just use your old WiFi base station for 801.11G/B networks and use the new D-Link for N only networks using the faster 5GHz frequencies.

They will not interfere with each other, your Pismo will function, and you will not be dumbing down your MacBook to use slower 2.4GHz N speeds.

Configure the old B/G base station so that it is in "Bridge Mode". There may be an explicit "Bridge" configuration option, or you may just need to disable DHCP and NAT services to get it into "Bridge Mode". That way you only have a single router on your home network and bonjour messages are not blocked because they can not cross a router boundary, but they are happy to cross a bridge.

I tried the "guest zone" with both WPA and WEP passwords, but encountered the same problem. The original post makes it sound so simple to change the WLAN mode of B, G, N to just B and G. How do you do this in Firmware Version: 1.32NA??? I don't need my older mac to connect often so I would just switch the router when I need to connect (if that is possible). Did most of you just use your older router as a bridge?
Thanks,
Marc
