I have the D-Link DGL-4500 since 12/08. It have been working great until a couple of weeks ago. I can't connect to my wifi 9/10 times and when I do, getting request time out. This is happening to my 2 laptops and my Linksys router acting as a client bridge. I have no cordless phone, microwave, or any other 2.4ghz devices nearby. The only wireless device is my Logitech MX Revolution mice. I have tried every channels, no luck. I did a reset of the modem, same result. Was using firmware 1.15 but decided to upgrade to 1.21NA even though I read so many bad things about the 1.2x firmwares. Still no luck.

Did some more troubleshooting yesterday. I reset the modem again, but this time kept everything default to keep it simple. In this scenario, I have no problem connecting and can keep a continueous ping going. Then, I set the security to Auto WPA or WPA 2. Connection and ping still good. Changed the default SSID from dlink to Starwars (I know it's corny). I can't connect anymore. Changed the SSID back to dlink. Connection is on and off and ping reply only about once per every 10 timeout. I changed the security to WPA only and static set the channel to 10. This seem to give me a connection 8/10 times and I am getting timeout once every 4-5 reply. I noticed that when my wifi is security free, it's 100% signal since I am only a few feet away. Once security is enabled, my signal drops to 60's % range.

I know interference can be the culpit but I am not sure about that. From what my laptop can scan, the 8 other wifis out there are using mostly channel 6 and then 11. I see no one else using 1-5 and 7-10. Also, it seem like when I enable security, it might be working the router harder thus the crappy wifi performance. Doesn't this sound a router about to get worse?

I'm baffled...if you read about the 1.2x fw and still decided to flash to it then...well I'll leave it alone.  Have you called d-link up and explained your problem?  They might send you a new router and if they do I would hope that you never flash it beyond any firmware that you can't roll back.  D-link sent me a new a2 which I keep at 1.16b3.

Call D-Link cs, ask for 3rd tier support. You will only be wasting time having the 1st and 2nd tier read you a script in bad English.

Also using any channels other than 1, 6, or 11 is not a good idea.

I haven't call tech support yet. I did email them yesterday. As to the firmware upgrade, why not when things are not working. What do you have to lose from that point on?

I have it on channel 1 even though no one else is using it. No difference.

Finally got my D-Link replacement. Came with firmware 1.12, version A2. The wireless is definitely better now than the old one but comparing to my old Linksys WRT54G routers, not as stable. When I setup my Linksys router as an AP, I can contineously ping it forever without a request time out. With the new D-Link, I might get 4-5 request timeouts per minute. If it gets worse like the old, I am going to just use my Linksys as the AP and keep the D-Link as the wired router.
