  1. Get rid of that stupid annoying warning about “Moderate NAT” on XBOX 360 (XBOX Live)

    May 30, 2011 by Andrew Block

    Despite forwarding all of these ports to my XBOX 360 and even enabling plug and play on my router, I could never get those annoying “Error: Your NAT type is set to strict (or moderate)” XBOX Live warnings to go away.

    The ultimate solution for me was to put my XBOX 360 on my router’s DMZ (De-Militarized Zone). Keep in mind I’m running DD-WRT, so your settings might look a bit different.

    Here’s how:

    1. Make sure you manually assign your XBOX an IP address via your router’s DHCP interface. Again, do not manually assign the IP address on the XBOX itself, but use the DHCP settings in your router to assign a static IP to your 360 (EDIT – actually, this doesn’t matter. Either way, manually assigned on the console or via DHCP, works).
    2. Go into the section of your router where you can assign an IP address to the DMZ. In DD-WRT, it’s in NAT / QoS -> DMZ. Click “Enable” next to “Use DMZ” and enter the XBOX 360′s IP address. Click Apply Settings to save your changes. Here’s a post how to do it on the vanilla Linksys firmware.

    Aaah, no more friggin’ annoying Moderate NAT warnings! Now keep in mind, putting something on the DMZ is the same as having no router in front of it, so be sure you’re aware of the risks (in my estimation, it’s not a big deal on the XBOX, but I would NEVER do that on one of my PCs).

  2. Use Apple Airport Extreme to add a second 5 GHz N-only wireless network

    May 30, 2011 by Andrew Block

    I inherited an Apple Airport Extreme from a friend of a friend, but already had a Linksys WRT320N that was working fine (well, after much hair pulling). I was initially going to use the Airport for shared network storage, but that proved too buggy to be of any real use. Since the WRT320N isn’t simultaneous dual-band, I decided to use the Apple to add a second, 5GHz + N only wireless network to my setup. Here’s how my setup looks:

    • WRT320N (running DD-WRT): Handling DHCP; running 5GHz wireless N-only network
    • Airport Extreme: Access Point; running 2.4 GHz N/G mixed network

    Here’s how I did it. First I changed the WRT320N to broadcast 5GHz + N-only, and I appended “-5ghz” to the SSID (so it reads like network-name-5ghz). Only a few of my devices can take advantage of that, but I mostly wanted it for faster wireless gaming on my XBOX 360.

    Then I got the airport up and running as an access point. Here are the key settings to do that. You first need to download and install Apple’s Airport Utility (the latest version is 5.5.2, as of this writing). Once you’ve added the device to your network and the Airport Utility recognizes it, go to Manual Setup, which is a button at the bottom. Note: If you need help with the initial setup, here is Apple’s user guide.

    AirPort section

    • Wireless tab: Create a wireless network here. In my case, I set the Radio Mode to “802.11n (b/g compatible)”. This allows all of my non-N and/or non-5 GHz devices to access a wireless network. I gave it the same name as my 5 GHz network, except I dropped -5ghz off the end.

    Internet section

    • Internet connection tab: Connect Using should be set to “Ethernet” and Connection Sharing should be set to “Off (Bridge Mode)”.
    • TCP/IP tab: I did configure IPv4 “Using DHCP” but you can manually assign an IP address, too (My WRT320N hands out IPs, some of which I make static for port forwarding purposes).

    That’s it! This should allow you to have your Airport Extreme act as an Access Point, and broadcast a second, uniquely-named wireless network. I’ve noticed a significant reduce in lag and latency using 5GHz for XBOX Live, and since the networks are on different frequencies (5GHz vs. 2.4GHz), the signals don’t interfere with each other.

    Note: My iPad and Gateway laptop are the only other devices that can “see” my N 5GHz-only network. A lot of wireless N adapters can only do 2.4 GHz, sadly, so they get relegated to the AirPort’s mixed network.

  3. How I fixed my Linksys WRT320N’s speed issues

    April 7, 2011 by Andrew Block

    I’ve got a Linksys WRT320N. I’ve never really liked it…seems like after a while, the performance of my network always started to degrade, and I always had to reboot the router to get it back to normal.

    So then I thought about getting a new router, but I had (at the time) invested a decent amount of cash for the WRT320N, so I decided to try a custom firmware instead. I ended up going with DD-WRT. Installed fine and was up and running in no time.

    To fix the performance degradation issue, I set the router to reboot automatically every night at 4 a.m. Not the most glamorous solution, but it gets the job done for now. To do that in DD-WRT, I logged in to my router’s IP address, then it’s under Administration > Keep Alive > Schedule Reboot.

    Hey, whatever works right?

  4. How to uninstall Symantec Endpoint Protection 11 WITHOUT the uninstall password

    March 7, 2011 by Andrew Block

    So you inherited a PC? Sweet. But dang, it has Symantec’s crapware Endpoint Protection 11 on it. Tried uninstalling, but you need a password? Don’t know it? Sorry dude.

    Actually, there’s good news. There is a way to remove SEP 11 without the password. The first (and easier) way is detailed here. Unfortunately, that way didn’t work for me (I think Symantec disabled it in an update), so I found another way to remove it.

    Disclaimer: Don’t do this on a work-issued PC. Your company may have policies about such things, which, if violated, could get you in trouble.

    Steps to remove Symantec Endpoint Protection 11 WITHOUT knowing the uninstall password:

    1. Click on Start -> Run (or Window Key + R if you don’t have the Run menu item)
    2. Type smc -stop. If it prompts for a password, open regedit (Window Key + R; type regedit; hit ENTER) and then navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC. Look for the smcexit key, delete it, and then type smc -stop in the Run box again. Note: my key was called smcexit-test or something like that, but deleting it had the same effect.
    3. Now, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC. Look for the smcinstdata key; delete it.
    4. You should now be able to use Add/Remove programs (or Programs & Features in Vista & 7) to remove SEP 11 without supplying the uninstall password.
    5. You’re now free from the shackles of Symantec. Enjoy a 10-15% performance boost. :)

    For a free replacement antivirus/anti-spyware program, I’d recommend Microsoft Security Essentials. I’ve used it for a couple years with no problems, and it seems to go easy on my system resources.

    Did this guide work for you? Let me know either way below.

  5. Extract images from Microsoft Word 2007 / 2010 documents, the easy way

    February 18, 2011 by Andrew Block

    So, I had to put together a user guide for work. I used a bunch of screen shots that I had capture with SnagIt, and pasted them all directly into the rather lengthy Word doc.

    But, when it came time for the designers to actually make the guide pretty, they asked me if I had saved the images anywhere. Oops! I needed to figure out a way to extract the images from the Word doc somehow — and quickly! As always, Google was my friend.

    So here’s what to do (only works with Office 2007 and up): make a copy of the Word document, and change the extension of the newly-made copy to .zip. Now open up the new .zip file, go into the ‘word’ folder, and then into the ‘media’ folder. You’ll see that all of the images that are in that document should be in that folder, as PNGs. The other nice thing is, they are generally in the right order that they appear in your document.

    So that’s how I saved my butt from having to re-do 50+ screen captures. Maybe it’ll save yours, too.

    Questions? Something I wrote doesn’t make sense? Let me know below.
