Yes. You have a really old wireless router. I remember when I had that same router -- the wireless radio eventually stopped working. I replaced it years ago. A new router should give you a stronger signal and better security.
The broadcast/aspect part threw me off. I just call it turning off the wireless radio.
Most wireless routers will let you turn the wireless radio off with a simple toggle option, usually on the same page as the basic wireless settings with the security options.
I've been ocupied and thus have not upgraded my firmware to DDT, but strangely now I don't think I need to. To put it simply here was the problem: My PS3 was losing it's connection wirelessly every now and then, and my computer's wireless activity did the same. This set off an alarm for me stating the problem was my router. Indeed it was, because I may have found the solution. I have been on my PS3 for a full day now, and neither my computer nor my PS3 has disconnected. The solutioin? Switching my linksys router from "mixed" to "G+B" mode AND putting it on channel 11 instead of the default 6. That seems to clear up any dropped connection issues. I'll test this for a few more days and if everything runs perfectly then I shall report back here.
DDT is the pesticide. DD-WRT is the firmware.
If you want wireless N back, then try DD-WRT. You basically have to reset the router to default settings with the reset button, upload the starter firmware ("newd_mini") from the WRT150N wiki page, reset the router again, and load the newest full firmware. The WRT150N is a lot easier than other routers I've reprogrammed with custom firmware.
I could use some major help. I've put about 8 hours into this the last two days.
My PS3 has run on Wifi for the last 1.5 years or so with no problems. Suddenly I've been having problems staying connected to PSN and a bunch of media server errors. I started by rebooting my router/modem (Verizon DSL) and restarting my PS3. I've try setting up the network with 'Easy' settings, and with 'Custom Settings'. I've gone through ever combination of router and ps3 for the dmz, upnp, and other settings. I've also turned off the media server. I've even completely reset my router to factory defaults and formatted the ps3 out of desperation.
Sometimes on a fresh reboot, the PS3 instantly connects the PSN and it looks good, but the first time I goto the PS store, or even test network settings, it signs me out of PSN and I am unable to reconnect. I've seen about 6-7 different error codes.
The strangest thing is that after I get disconnected from PSN and I log into my router, it shows my PS3 connection as ethernet (instead of wifi) and that it is disconnected. When i reboot the PS3 I instantly get reconnected to PSN. I goto internet connection test and get disconnected from PSN, and now I can't even obtain an IP address.
Once I rerun set up and go through a few reboots I can probably get back into PSN, but it's a never ending cycle.
Any help would be appreciated!!!
