Im trying to stay at a budget of around 900 dollars, so the 4870 would go way over that. thanks anyways

I will have internet access for about 24 hours and then suddenly the router will stop broadcasting the network. I can still see my network listed amoung the Available Networks but my laptops will not connect to it. I cannot see my other computers either. My desktop computer which is connected directly to the internet with cables (thru the router) still has access.

I am using a Netgear WGT624 v3. I have called the company twice. The first time they changed my security setting to WEP instead of WPA-PSK. The second time they changed my MTU Size from 1500 to 1300. Still not working consistently.

Is this a hardware problem? I used to work for a company that set up a wireless network that would shut itself down occassionally because data would get stuck in a never ending loop and overwhelm the system. Not sure how that could happen here but the symptoms are the same.

How do I find out if I have WEP, or Wpa-PSK (TKIP), all that? and the password for it?

I have a gateway windows vista computer if that helps.

I have a Dell Dimension 8300 that has been beefed up to 768 MB RAM running on Win XP SP2 and I’m using a D-link Airplus g dwl-g510 PCI card and a Dynex Wireless G Router. I hooked everything up, got it all configured and it works GREAT! Never a dropped signal or any disconnects. I enjoy the Netflix “Watch Now” feature through this connection and the movies never stopped. I \had NO problems what-so-ever, until I decided to secure my network.

NOW… I take my old PC and connect it directly to the wireless router, so I can configure it for security. I set up both my router AND my PC/card for:
Network Authentication: WPA/PSK
Data Encryption: AES
Then input my OWN “Network Key” which is a alpha/numeric/special char combo, so is pretty secure.

AGAIN…. everything works fine, I log onto the system and it’s running great…. for a few minutes, then I lose the signal and have to click on the icon in my task tray and RECONNECT.

At first I thought I might be an issue with cable/internet signal strength, since there’s only ONE cable input into the apartment and I’ve had to split it several times before it reached my back bedroom. So, I moved my cable modem and wireless router to the main cable input into the apartment, but it’s not doing any better.

A REAL PAIN IN THE RUMPUS! Would a firmware update on either wireless component help? I see other wireless networks within range of me, which means they must be in my apartment complex, but I think they maybe using a lesser security setting, since theirs are not identified as WAP, like mine is in the display.

Any thoughts? Suggestions? Help? Greatly appreciated…

Is it possible to hack a network instead of a computer so that all the data's transfered thru a sniffer (for example)? I have a secured (WPA-PSK) wireless network with 4 other computers using that wireless netwrok. I have a firewall (ZoneAlarm) on the highest settings (stealth mode) on each computer as well. I use firefox, don't open any email attachments and am very specific about whose email I choose to open. How else can any hacker intrude? Would it still be possible to install a prog remotely (without a popular trojan perhaps). Wouldn't I be able to see if some sort of notification if that were to happen? I'm paranoid because I know some people that always end up doing the same things as me because of the activity on my computer (& they're shameless to copy what I do and then tell me about it instead). I think they are tracking what sites I visit, what I type (including forms on an internet browser, what I view, etc. I'd like expert advice from a network security analyst possibly.
So those open ports vulnerable even with a firewall? Would they be outgoing or incoming ports? and are they UDP or TCP? Because I can list ports I want to block on Zone Alarm. But is it even effective blocking through ZA? What's the best way to scan and block those ports?
And what are the following ports for (listed in ZA firewall settings)?
-outgoing NetBIOS (ports 135, 137-139, 445)
-incoming ping (ICMP Echo)
-outgoing ping (ICMP Echo)
-other incoming ICMP
-other outgoing ICMP
-incoming IGMP
-outgoing IGMP
-incoming UDP
-outgoing UDP
-incoming TCP
-outgoing TCP

And which ones should I block without completely comprising functionality?
