Re: Keeping Your Wireless Network Secure

What I do to have a secure network is enable MAC filtering and permit access to those MAC addresses that are in the list. I have read that MAC addresses can be spoofed. I don't know how easily. What I know about network security is what I read. I took some Network classes. All I learned was what I read. I could not get a demonstration on getting into a wireless network, just for Internet access. I think this would be a valuable part of the class. As a Techie, I don't learn well just reading, I need hands on exposure to. Practice what you learn...

I also set a maxium number of IP addresses that the router/gateway can issue. My current router has a default of 50 IP addresses to issue. I lowered it to 2. I believe this would frustrate all but the most serious/determined WiFi freeloaders/hackers.

What I don't know is when someone in range sees my network as available with WPA2 security, what happens if they try to connect? When I connect, my network key shows up as dots, click connect and I'm on. I am guessing/hoping my network key is hidden on my computer in a configuration file of some sort. If another device clicked connect, it would ask for the network key and confirmation.

My WiFi N adapter using an N router shows 150 Mbps as connection speed. I don't understand how WiFi can be faster then the Ethernet, since the Ethernet provides the speed to the router. But I don't feel any performance improvement either. Speedtest doesn't show faster speeds either. So IMO, it's hype

My adapter is a 150 Mbps adapter. N adapters can be 300 Mbps to. I cheaped out and got the slower one !!!! But it doesn't seem a 300 could get me better performance though.

Re: Keeping Your Wireless Network Secure

I have tried disabling SSID Broadcast before. Expecting that to mean, someone in range can't see that I have wireless available. But then, how do I sign into my own network???

Thanks

Re: Keeping Your Wireless Network Secure

Thanks for making me try it again..... I had a belkin router before that I tried disabling SSID broadcast. I didn't spend much time trying to figure out how to get into my own network..

Now, I have a Linksys/Cisco router. Tried disabling SSID broadcast and made sure the adapter was set to "connect even if not broadcasting".

In 10 minutes, I was able to find what I needed to find (connect even if not broadcasting) and I'll be darned, I can connect to an invisible network...

As I tinker around with home routers, I find that being familiar with the configuration s/w is half the battle.

Thanks
Rick

Thanks

Re: Keeping Your Wireless Network Secure

But it's not invisible. It's just that no name in being broadcast and Windows has made it so that it doesn't pick up on such networks and show them. Other programs can and do.

True. Always other tools available. I don't know them though.

Now I am really confused. When I have my desktop wireless, and view available wireless connections, mine doesn't show up. Which is what I want. But my laptop it shows it shows up. The laptop adapter is set up the same. Connect when not broadcasting and connect when network is in range....

If I uncheck those options and check them again, then it won't show up. It's like the adapter doesn't remember those options are checked. But it only lasts a few minutes. If I refresh network list, it shows up again..
I guess the adapter has a short memory

I can't get support from Linksys since I am not the original purchaser and it was bought 2 years ago... Hopefully, I can get a customer to have me set up a network with a Linksys router and I have the same issue.... Get support from them for my clients router and me too...

It's a bit late but here goes. I was not referring to the theoretical rated speed of the router or the Wifi connection. The 51Mbps over wired and ~20 Mbps over Wifi are real data transfer rates measured using a 250 MB sample file download (with Internet Download Manager @ 8 Split parts).

My laptops enternet is Gigabit and the WiFi router is rated 300MBps. Clearly the rated speeds doesn't mean much.

I assume that you have the SSID broadcast disabled in your router's firmware. It means your Windows laptop or PC won't be able to see it and connect to it.

I think you have the Wireless connection set up properly in your laptop and it is behaving as expected. In your Desktop, you can add the connection manually by typing in the SSID and it should connect to the router even if the SSID is not being transmitted.
