Your PS3 should be able to check the strength of the signal your router is sending. It should be fairly high – above 85%; my signal is usually in the 90’s.
The more material/walls a signal has to pass through, the weaker it gets. Passing through two rooms shouldn’t weaken it that much.
If your signal is falling off, not in that high a range, it’s time to change your router.
Trouble-check your Router first – yes, dig out the old instructions and do what they say!
[This year alone, I’ve had 3-4 different pieces of hardware (mouse, keyboard, monitor) fail on me after years of service. Everything eventually breaks!]
To be honest, if you are connecting normally, and downloads are stopping, your Router might be going bad. I’ve had success with my D-link Router but other people say that D-link is a bad brand. I dunno – I figured it out. In my experience with PC hardware, HP has been far worse! LOL
You may have to reset your Router through your computer which unfortunately means changing your WEP/WP key. Whatever you choose (type) as your new Key, write it down or print it out so that you can retype EXACTLY-AS-IS for your PS3. It’s 32 or 64 characters of pain but that’s what keeps Tommy-boy next door from stealing your credit card info or getting a free ride onto the Net.
Your WEP/WP typed into the PS3 must be the same otherwise the Router will not allow the PS3 to access your wireless network…
Setting up routers and wireless networks can be a pain-in-the-boot. It took me two tries to get this right with my PS3!
(( **** Unless you absolutely have to, NEVER EVER return a PS3 to factory state. It will wipe out your Wireless Set-Up info and you’ll have to start all over again. I learned that the hard way!!! **** )
Most of the set-up is common sense but there are a few gotcha steps that can get you if you don’t check the right option. Keep track of what you choose for options (WRITE THE STUFF DOWN; few of us have photographic memories) so that you can backtrack and trouble-shoot the PS3.
If you’ve tried again and again over a few days, get a buddy who knows about Routers to help. You just might be skipping a step. IF after a week or so you still haven’t figured it out, that’s when you should seriously start thinking about getting a new Router.
