Factory reset of the router (using the button on the back, pressed for at least 10 seconds).Then I followed this procedure (using instructions found on that site and some instructions found on some other forums): Since my firmware version was 1.x and I was updating to version 2.x, as reported in the documentation in that site, I could not use the web update procedure, but I should use the EXE version, so I downloaded this zip file, which contains the. However, since the router was not working perfectly for me I decided to have a try: if the router was ruined I was willing to buy a new one :-) I was quite skeptical in trying to update the firmware (the last I had tried this procedure I ruined my previous Atlantic router), furthermore, the firmware in this site is Australian and in the readme file you read that this was tested only for Australian router. In particular, here I found a quite new firmware version for my router revision (A): V2.00B12.AU 20070509. However, by googling I found this site that was referring to a D-Link site which still provides some information and software about this router. I checked the D-Link home site only to discover that this router is not maintained any more ( discontinued product) and indeed I couldn't find any updates for it. I also tried with some wireless settings of the router (also using WEP and WPA) but nothing was changing (and the wireless embedded card in my laptop is actually OK since I was reaching very high speed with other wireless networks). I've been using this ADSL wireless router, D-LINK DSL-G604T, for almost one year now and I was quite happy with it, unless I discovered that the wireless connection provided by this router was not very good: my ADSL is 4Mb (and indeed with the wired connection I was reaching the full speed, ~500K) but with the wireless connection I was hardly reaching 100K speed, so the wireless connection was pretty slow.
