Anyone have first hand knowledge of the peformance expected from any 802.11g?

we use it on a limited basis at my workplace..and in comparison to our lan lines..its nearly indistinguishable.. mostly because the support laptops we use, dont travel that far beyond the wirelss router and access points. The only difference i see is when we have attempted to ghost up backup images off of user's laptop hard drives..that is a bit slower as we have 100mb throughout our building and g is not quite that fast.

Thats my basic expience with it.. easy to setup and great for surfing - your basic stuff...

someone else im sure will quote you the statistics of it so i wont here..

I don't have a G router but PLEASE make sure you set up all the security. Filter MAC addresses, disable broadcasting of ssid's, and use encryption. I found a strange computername in my dhcp tables a few months ago. I do live in a townhouse so our units are VERY close. But it is still distressing to see that.

HaVoC, I heard that .g is incompatible with 2.4 ghz phones. My boss loses his network connection when a 2.4 cordless phone goes off-hook.

Yes!! Our CEO had that problem. He was NOT happy. We backed him down to 802.11B instead.

yes the g has serious problems with certain phones in the house,

A will work too, but it has a shorter range than the others I believe and it is more expensive.

All you never wanted to know about 802.11g

- 802.11g has a maximum rate of 54Mbps. However, due to a number of factors that has to do with RF transmission, you will likely get ~24Mbps - still pretty darn good.
- 802.11g does operate in the 2.4GHz spectrum, which means it is susceptible to interference from: 2.4GHz cordless phones, 2.4GHz baby monitors, 802.11b wireless devices, some microwave ovens, etc. The 2.4GHz spectrum is getting pretty crowded because it is unlicensed and radios are pretty cheap.
- 802.11g has an advertised range of 300 feet, however, you'll get maximum throughput for about 50 feet depending on the environment (walls, floors, ceilings, construction materials, etc.). After 50 feet, you'll get about the same throughput as 802.11b wireless devices (<11Mbps)
- Wireless communication uses CSMA without the CD - which means it is half-duplex communication.
- WEP is not very secure. It can be broken by many free programs out there. That said, use it anyway to keep out the casual hacker. If your unit has MAC address filtering, use it too. Doing this will only allow devices with the specified MAC addresses to access the AP. This is also easily spoofed, but not by the casual hacker...

802.11g and 802.11b operate in the same spectrum. It is likely that the 802.11b unit that you put in (because .11g had an issue) operated on a different channel. There are basically 11 different channels that can be used (there really are 14 - but we won't get into that...). Three are non-overlapping (don't interfere with each other) 1, 6, and 11...

802.11g is backwards compatible with 802.11b. 802.11a works in the 5GHz spectrum and is less susceptible from interference from other radios, has more available channels, but is more susceptible to environmental interference. Also, it is not compatible with .11b and g.....

Havoc,

My practical expericence with the Netgear WG602 Connection Point

I had it for about a year, and use one at work and home with my dell laptop (using the dell minipci G card)and it works well with no external antenna on my laptop.

With all said about security issues, If you live in a single dwelling house you should have no problems security wise. The signal is strong with 54 mbs almost everywhere inside my Cape and within 10' outside on my porch swings. at about 30' i drop off to 20ish and at my sidewalk 50' i barley get a signal if i dont sneeze at 1mbs.
My cape has aluminum siding, i think this cuts the signal a bit. At work my range is greater even with floresent lighting, I get a good 75' with 45mbs connection at my confrence room.

Also the signal travels downward alot better then up so mount it high or on a second floor. When i put it in my basement i had poor signal strenth and Speed on my 1st floor @10mbs, so i moved it into a corner of the entertainment unit on the 1st floor and WoooHoo. At work my office is on the 1st floor in an old 1960 building with a Atomic Bomb shelter basement (yea what good was that really?) it about 2' concrete between floors to where my Junk storage is right under my office. I had 54mbs signal in Excellent connection. I stayed down there a lot longer then necessary cause it was so damn quite.

As per 2.4 Gighertz phones. I have the 2.4 Vtech w multi handsets at my house and they never pose a problem. I use them, surf at the same time never been an issue. However at work i have the Panasonic 2.4 Gigarange Extreme... This cuts the signal as soon as the phone rings or you place a call, and i imediately reconnect once the phone hangs up.

Sometimes ive found i need to reboot the Access point by remove the power cause it wont let me connect. I dont know if thats because i use my laptop at work and home so it gets confused authenticating all the time or what but probably done that 2'x at both locations.
