hi, im running a wireless network at my house and i'd like to know if encryption would have a negitive performance effect on my ping in a video game?

basically what i want to do is keep my router hidden/unaccessable to the outside world.

any help/idea's would be greatly apperciated.

Yep, WEP or WPA will slow things down, sometimes by a significant amount. That will depend on the specific equipment in use.

Not really. For a wireless network, some sort of encryption is about the only real protection you have.

Here's some of the suggestions you'll receive, and why they're bogus. :)

MAC filtering: This is like handing a security guard a pad of paper with a list of names. Then when someone comes up to the door and wants entry, the security guard looks at the person's name tag and compares it to his list of names and determines whether to open the door or not. Do you see a problem here? All someone needs to do is watch an authorized person go in and forge a name tag with that person’s name. The comparison to a wireless LAN here is that the name tag is the MAC address. The MAC address is just a 12 digit long HEX number that can be viewed in clear text with a sniffer. A sniffer to a hacker is like a hammer to a carpenter except the sniffer is free. Once the MAC address is seen in the clear, it takes about 10 seconds to cut-paste a legitimate MAC address in to the wireless Ethernet adapter settings and the whole scheme is defeated. MAC filtering is absolutely worthless since it is one of the easiest schemes to attack. The shocking thing is that so many large organizations still waste the time to implement these things. The bottom line is, MAC filtering takes the most effort to manage with zero ROI (return on investment) in terms of security gain.

SSID hiding: There is no such thing as "SSID hiding". You're only hiding SSID beckoning on the Access Point. There are 4 other mechanisms that also broadcast the SSID over the 2.4 or 5 GHz spectrum. The 4 mechanisms are; probe requests, probe responses, association requests , and re-association requests. Essentially, you re talking about hiding 1 of 5 SSID broadcast mechanisms. Nothing is hidden and all you ve achieved is cause problems for Wi-Fi roaming when a client jumps from AP to AP. Hidden SSIDs also makes wireless LANs less user friendly. You don't need to take my word for it. Just ask Robert Moskowitz who is the Senior Technical Director of ICSA Labs in his white paper Debunking the myth of SSID hiding.

Disable DHCP: This is much more of waste of time than it is a security break. DHCP allows the automatic assignment of IP addresses and other configurations. Disabling DHCP has zero security value and just wastes time. It would take a hacker about 10 seconds to figure out the IP scheme of any network and simply assign their own IP address. Anyone who tells you that this is a way to secure your wireless LAN doesn’t know what they’re talking about.

thanks for all that info johnwill, i recently seen a streaming video on win amp's internet t.v. about wireless hacking (actually there's 2 now) and i've become more interested in wireless security because of it. i may enable wep and see what happenes to my game proformance.
