Connecting Kindle WiFi over OSX Internet Sharing
Moving into a temporary rental has provided a few challenges. 1. to find a temp rental in the first place 2. find one that allows a cat 3. work out a solution to internet access for 2 Macs, 1 PC, iPad, iPhones, a Kindle & a Netgear NAS.
As you can see the whole family of devices needed internet and the only decent solution was a Telstra 4G USB modem. The USB modem works great, really excellent speeds in a great 4g coverage area. I’m talking 22MB+ down and about 14MB up. Sensational really as i’ve only ever experience at best 8MB’s on any wired net connection in any previous office. One downside is the cost, about $100 AUD for 6GB data and the other is sharing the connection across the existing network, WiFi and hardwired.
The solution: OSX Internet Sharing in Snow Leopard 10.6. I am absolutely stunned at how well this works. I fire up the 4G modem and then use internet sharing under preferences to setup the Wifi as a repeater and the Ethernet as shared also. Works great to a point, all my iOS devices worked brilliantly on WiFi and even the PC got internets straight away when connected via cable.
Issues i found: NAS didn’t want to connect.. sad times. So I had to set the IP address of it manually to the same subnet as the Ethernet 169.254.200.88. This worked fine, now my iMac the master sharer could access the NAS.
I found now that the Kindle could not. I read this post thanks to CodeGen which solved the Kindle problems by doing this:
You need to keep to the recommended length of password for WEP keys in your Airport Internet Sharing setup - 5 characters for 40-bit and 13 characters for 128-bit Eg ‘John5′
——————————————
The problem is that the kindle aways uses 0 in the “number of seconds since boot” field of the dhcp request packet, and the mac has a filter of 4. So it ignores the DHCP request from the kindle (and the xbox, and the Nintendo). If you change the filter to 0, then the mac happily hands out the addresses. How to do it:
1. start internet sharing
2. cp /etc/bootpd.plist . ## don’t forget the “.” that means the current directory!!
3. stop internet sharing
4. open bootpd.plist
5. change reply_threshold_seconds to 0
6. sudo cp bootpd.plist /etc
7. start internet sharing
Normally the bootpd.plist is created and destroyed as you start up and stop internet sharing. If the file already exists, it uses the values in it.

Kindle problem solved. I still however have the issue that the PC cannot access the NAS due to the IP address set by internet sharing which can be accessed by the above method. I’ll do another post on that soon.

VMWare Network Connection over OSX Internet Sharing
I had a problem trying to connect my VMWare session of XP over OSX Internet Sharing (ethernet adapter). I figured out that with a normal hardware you can use a bridged connection - Bridged (Autodetect), but when using over OSX Internet Sharing switch to NAT and your ethernet will then start working. Like Magic!
VMWare 3.1 running Windows XP Pro SP3
OSX Internet Sharing 10.6 Snow Leopard

GoPro Hero2 Fog Up Problem Solution
GoPro Hero2
Now that I have my shiny new GoPro Hero2 i’ve been out and about trying Time Lapse shots, some action video, underwater etc. Really good fun.
The issue I have using the housing is a fogging up problem. When using the waterproof housing you can get condensation build up on the inside of the lens.
There are a few solutions. One is to use the genuine GoPro Fog Inserts which retail for around $29 available online from Auski in Australia (Free Shipping) or the GoPro website + several others around the country.
While the inserts are said to work (i haven’t purchased them yet..) I have found another cheap solution when not requiring you going near the water.
I use the LCD Backpack with my GoPro which has various other housings in the box, one being the non-waterproof vented cover. Using this cover allows air to get inside the housing making it NOT fog up. Great cheap fix.
The other solution i have is to simply open up the back cover and keep it slightly open allowing air to flow inside, again not allowing it to fog up. All i did was unlock the black top clip and allow the back housing to rest on the clip.

Hewlett Packard HP Color LaserJet CM1312nfi USB Not Installing
Recently had a client who we were helping out with a new HP CM1312nfi printer onto a Windows 7 PC.
While the printer used to work on XP no problems with the disc supplied, i had to download a new Windows 7 full package (306meg) from HP and install it that way along with a couple of extra settings.
Turns out the correct Windows 7 software would not pickup the USB printer when it was plugged in (when prompted by the installer software). The install was around 94% and had to cancel and figure out why.
So the steps I used to get the HP CM1312 working with Windows 7 are:
HP CM1312 64bit WIndows 7 Retail install.
1 - Download: CM1312series-win7-full-solution-AM-EMEA1-v5.1.exe (308 MB)
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=18972&prodSeriesId=3558902&prodNameId=3562006&swEnvOID=4062&swLang=8&mode=2&taskId=135&swItem=tw-77243-1
2 - Right-click the file and select “Properties.” Click the “Compatibility” tab at the top of the resulting window.
3 - Check off “Run this program in compatability mode for:” and choose “Windows Vista” from the pop-up menu.
4 - ALSO check “Run this program as administrator” at the bottom of the window.
5 - Press “Apply,” then “OK.”
6 - Now you can double-click the “Setup” file and run the software installer.
* I followed most of these steps to successfully install the printer, but at step 3 the option to change the compatibility mode was greyed out but Vista was selected.

iMac 24″ Condensation Problem
I recently got back from a trip down south and ran out the door leaving the Mac on sleep mode.
After using it for 20mins i noticed condensation covering about 25% or so of the glass screen in the bottom right.
The weather was very humid as this area just had 4 days of rain and the air conditioner was not running.
I used a hair dryer on cool mode in the vents at the rear of the Mac and turned the air conditioner on. The machine had about 15 apps open and was running pretty hot.
Once the humidity came down a bit it took about 45 mins for the condensation to disappear in full.
I read the Apple Support forum on it and others have had the same issue and leaving the unit on for a few hours will fix the problem.
I assume running your machine day to day it wouldn’t occur too often.
