* Test Vector: '123456789' (character string, no quotes)
* Generated CRC: 0x29B1

* CRC16 Lookup tables (High and Low Byte) for 4 bits per iteration.

Stafford Regional Airport

Stafford Regional Airport: "Maximum Noise Level - Stafford County, Virginia has a community noise ordinance which establishes a maximum noise level of 65 dBA Single Event Noise Exposure Level (SENEL) from 0700 hours to 1900 hours local time, and 55 dBA SENEL from 1900 hours to 0700 hours local time. Compliance with the ordinance is mandatory unless deviations are made necessary by weather, ATC instructions or clearances, an in flight emergency or other safety considerations.

Customer Reviews Of LINKSYS WRT54GL Wireless-G Broadband Router - Retail

Customer Reviews Of LINKSYS WRT54GL Wireless-G Broadband Router - Retail: "Thank you Linksys

Pros: As the others have stated before me the WRT54GL benefits from the ability to be flashed with third party firmware. I would not recommend this router to someone who plans to use just the standard firmware, if that’s your intent I would go with the WRT54G. However, that being said this router is an excellent buy for someone with networking experience who wants an inexpensive router to do expensive networking tasks.

Like what you may ask? Well I may tell you that you can set up your own VPN server on this router, as well as a Samba or FTP server, it can perform as a bridge, it can boost wireless signals, it can be a Radius server, and I’m sure if you’re cool enough you can even get it to slice, dice and julienne. Those however are just a few of the extra features that you can add with third party firmware.

On top of all this you get one robust little machine. A 200MHz with 8MB RAM and 2MB of flash might not seem like a lot but it is more than enough for home or small office nee

Cons: The biggest con with this router is that by flashing it with third party firmware you void the manufacture’s warranty. On top of this, if done improperly or with incompatible firmware the router can be made into a fairly expensive paper weight and or doorstop. This is called “bricking” the router, recovery is possible most of the time and I’ve included a link below for how to unbrick the router. If this doesn’t appeal to you I would think twice before purchasing this router.

On top of this, most of the third party firmware out there will need some networking experience for all of their features to be fully realized. That being said this router is not the best for an inexperienced computer user.


Other Thoughts: My GL is currently sitting in my apartment running OpenWRT White Russian 4, an open source firmware which lets you choose which features to add ("
