2km wireless bridge

5.8 will not make that distance through obstructions. 900Mhz will, and 2.4G has a good chance. 900mhz will not get you a 50M link, and 2.4 probably will not either, since you will lose a lot of signal due to obstructions. You are probably looking at an effective speed of about 10M with 2.4

32-bit Office vs. 64-bit Office

We moved to x64 Office with 2010, and have continued with our 2013 rollout. Over 600 machines without issues. Of course, we have very few Office plugins, except for the Mitel and Panasonic PBX additions for the UCA function of our phone systems. All of those were upgraded to work with x64...

Cisco SOHO

If you want to try to learn something useful, try getting any of their small router line or go with a ASA series router/firewall. All of these are going to be more than the SOHO series, but you can find them pretty cheap used sometimes.

Quick PBX question. Are the processors swappable? Ours got fried

I work on Panasonic PBX systems, and a PRI card alone (for a digital circuit) has a MSRP of almost $2k. It is pretty crazy how expensive a business class phone system costs. I can say that the only time I have ever lost hardware is from power and surge issues!

are 2 small wifi antennas better than 1 large one?

The only way two antennas would be better is if it is a "N" wireless AP and it is using MIMO. Otherwise, if you want more distance, go with a slightly higher db antenna. I think the default antennas are 3dbi, so a 6dbi antenna would give you twice the total output. Say your AP puts out...

I have never relied on the certs, but I have just finished up my CCNP, and thought it was a valuable learning experience. I also have my MCSE/MCITP, Sec+, and Net+. I have gotten all my certs in the last 5 years, since I now have a training budget. Before that, I had only taken an exam when...

Need Cisco guru - screwed up 871 router

Yep. Just the fact that you are seeing gibberish means that there is still something left of the router software. Resetting it should have set it back to 9600/8/N/1 though, if it is like the 2600 series.

Antenna Radiation Pattern Concern

Don't worry about the vertical throw too much. As long as you have the antennas far enough away, you should be fine. On the other hand, you could always choose to add a Wi-Fi amp, but that would probably be overkill in your situation.

If you get a good, higher-end dedicated card (some of the Intel cards, etc) and get a switch that can accept jumbo frames, and enable jumbo frames on all your cards, you might get better performance. Kind of pricey for the intel nics though.
