Two wireless networks on the same subnet

Somehow, we ended up having two routers at home. The new one was a wireless N, the older one was a wireless G. To keep the speed on the wireless N network as fast as possible, I wanted all older laptops to connect to the wireless G router.

The problem was, with my initial setup, there were connection problems everywhere. Connecting from a laptop on the G network to laptop on N network worked. But not the other way around. Also, apple remote didn't work across the subnets.

I finally figured out how to solve the problem. Put them all on the same subnet! Here's how...



The trick is in the wiring between the two routers. And how DHCP is configured. See below...



Here are some more details, if you're interested:

Router1:
WAN IP: 10.1.1.2 (Depending on what ADSL modem wants you to use.)
WAN Subnet Mask: 255.255.255.0
LAN IP Address: 192.168.26.1
DHCP: Enabled
DHCP IP Address Range: 192.168.26.100 - 192.168.26.110

Router2:
WAN IP: 192.168.0.1 (Don't care. As long as it's not in the 192.168.26.* subnet)
WAN Subnet Mask: 255.255.255.0
LAN IP Address: 192.168.26.2
DHCP: Disabled
DHCP IP Address Range: N/A

Laptop on Wireless N:
IP Address: 192.168.26.101
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.26.1

Laptop on Wireless G:
IP Address: 192.168.26.102
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.26.1

I hope this helps. Enjoy!

Car Navigation Review: TomTom GO 930, GO 720, XL (30 series), Mio Moov 370

We were in search for a good GPS car navigation unit for use in Australia. Our three choices were: TomTom GO 930, TomTom GO 720, TomTom XL, and Mio Moov 370. Below is a review of what we liked and did not like about them.



Read on to know which model this is.

TomTom GO 930:
+ I love the black rubber finish. Feels less fragile compared to other TomTom models.
+ Has the superset of features for TomTom units: TMC, Bluetooth, FM, other common features.
- Very expensive

Conclusion:
Simply put, if money was not a consideration, I would have gone for this model. I have yet to see any real negative reviews about it other than its price. Plus while holding it with my own hands, it really did feel very solid.

TomTom GO 720:
+ Features: FM, Bluetooth
- Weak FM & Buggy bluetooth (So they claim)
- Pricey
- Forums report signal problems in Sydney CBD.

Conclusion:
The weak reviews and the price tag really did turn me off about this model. None of the features that distinguish it from XL or One XL seem to be any good. Furthermore, this old model seems to have an old GPS chip that is less sensitive compared to new models. My suggestion is to either go up for the 930, or go down for the XL.

TomTom XL (30 Series):
+ Value for money
+ TMC ready if you want to buy bundle
- No FM, No Bluetooth

Conclusion:
This is the model that we eventually decided to go for. We like the feature set. We don't really need FM or Bluetooth. And the price is acceptable. Plus the 4.3" widescreen is just the correct size, I would say.

TomTom XL Review 2


Mio Moov 370
+ Solid Feature Set. Pretty much equivalent to TomTom GO 930.
- Community support base

Summary:
Other than the fact that I haven't actually seen this exact model yet, I was a bit worried about the having community support for the product. I preferred to have a unit that has more user, more people adding corrections, more people creating POI entries, more icons, more sounds, etc. If you're not really concerned about the community support issue, then I think it's a really impressive product.

That's it for my review! I hope it helps. Now, if only we had our car already. =(

Google Chrome does not support ICC color profiles?

After the announcement two days ago, I was really looking forward to Chrome. Unfortunately, it seems to be missing on one of my most loved new feature of Firefox 3: support for color profiles.

See my post here and test it out for yourself.

Damn!

Control multiple computers with one keyboard and mouse

If you're geekozoid like me, you probably have more then one computer at home. And maybe even have them in a range of different operating systems. How do you control them from one source?

Well, there are plenty of options out there, like VNC, etc. But I just discovered one cool app: Synergy. I works for Windows, linux and mac. And best of all, it's free!

Check out my video below.

Canon EOS 350D on Vista 64-bit.

As of time of posting this blog entry, Canon still does not support Vista x64. Here's a trick that I found to work:

1) Install 32-bit Vista drivers. You normally get the EOS Solution disk with your camera body. Just use those.
2) Here is the magical bit... On your camera, change the connection mode from PC Connection to Print/PTP.
3) Now connect your camera to your Vista x64 pc.

Voila! It works like magic. =)

Enjoy!
