Alright, this is REALLY starting to get on my nerves, so hopefully someone can shed some light on my issue.
I have a Linksys WRT300N wireless Draft-N router with a 4 port switch. It is about 2 years old, and up until a month ago it ran flawlessly. Amazing little router.
About 25 or so days ago the router started just dropping the internet altogether - no other changes, just no internet. No apparent cause, nor any warning; just gone. Resetting the power fixes the problem, but it reoccurs randomly. Doing a reset via the physical button fixes the problem, but it still comes back. Same with the router software (192.168.1.1) reset option. And last night my XP laptop totally lost the SSID - the other wi-fi computers had it, and my wired PC had internet, but the laptop just kind of fell off the edge into a black hole.
No changes to the router password, no SSID changes, no security changes, just loss of internet. And it is the router, not the modem or the internet itself.
I am somewhat suspicious of the next door neighbors attempting a hack of our internet, as they also have a router (with WEP2 security) - however I seriously doubt that they set it up themselves (Geek Squad, perhaps). I have beefed up the wireless security to WEP2 on our end as well, changed the router admin password and the password for wireless access. I will also go back to my old "difficult" setup of hiding the new SSID once the computers are setup, and also only allowing MAC addresses of our computers.
I still don't really think it is a repeated hacking attempt or DoS attack, but just a glitch in the router itself maybe. I am using the latest firmware (a year or so old, but still the latest)... and I have looked into open source firmware for Linksys routers, and it only works for the G series (and I have a WRT150G or something, our last router, but I need the speed/range of N, not G "with SPEEDBOOSTER").
Ideas? Thoughts? Advice?
