Is 802.11b/g faster then 802.11g

The wireless network I have at my house has two Powerbook G4s (Both with Airport Extreme Cards) connected to it and I am wondering if Switching to 802.11g is faster then 802.11b/g. I dont have any computers connecting that need 802.11b.
Thnx

OK, Just to give you an idea about the difference between the 2.
If you are accessing the internet and downloading things and only have a DSL connection or just ordinary dial up then you may just as well set your Macs to 'b'. Signal/Bandwidth strength is greater with 'b'. Most dial up is '56k' and mmost DSL is 512 to 2mbs. So just using 11b is more than plenty. But if you have DSL from 8 up to 24meg speeds then 'g' is what you should use. But remember that the '54' speed is only the transfer / communication speed between 2 points. You can transfer a large file say a CD of music from one iTunes on one Mac to another Mac (example) and use 11g. You could of course double this by using a ethernet connection between the 2 Macs at 100mbps or even Firewire at 400 ot 800.
So in a nutshell use 'g' if you are transfering large data file and need to minimize time. But then of course you will do what suits your environment best.
Cheers

Connecting 802.11b/g devices to an 802.11n AirPort network

I have a Time Capsule with an iMac and a MacBook connected to it. I want to add a Windows laptop to the setup, but it only has 802.11 b/g networking built in. As I understand it, adding an 802.11b or g device to an 802.11n network will slow the network down to the speed of the slower b or g device. What kind of 802.11n device, that is compatible with the AirPort (Broadcom?) chipset, should I get to connect this computer to the network? (The PC does not have a card slot.)
Would an AirPort Express work in WDS mode, with its Ethernet port connected to the laptop's Ethernet port?

As I understand it, adding an 802.11b or g device to an 802.11n network will slow the network down to the speed of the slower b or g device.
Not quite all the way down to 802.11b or g, but there will be a bandwidth degradation for 802.11n clients.
What kind of 802.11n device, that is compatible with the AirPort (Broadcom?) chipset, should I get to connect this computer to the network?
A number of vendors, specializing in networking equipment, offer 802.11n USB wireless adapters. I have used a number of Cisco/Linksys products that work just fine with AirPort networking.
Would an AirPort Express work in WDS mode, with its Ethernet port connected to the laptop's Ethernet port?
If this AirPort Express Base Station (AX) is a 802.11b/g version, then it would have the same affect as any other 802.11b/g client. In fact, in a WDS, the network will only operate in the 802.11g mode, so you really don't to go that route either. Another option, would be to use a newer 802.11n AX; reconfigure it as a ProxySTA, and use its Ethernet port for the connection to the PC.

Airport Extreme Problems with 802.11b router

I have a Netgear MR314 LAN and wireless router. I have a G3 iMac and 2 G3 iBooks with Airport Express cards and they work fine with the wireless connection with this router. I have a 12 inch G4 iBook with an Airport Extreme card running 10.4.3. Every time when this iBook connects with the wireless router it works for about 10 minutes and then the router locks up. If I re-set my cable modem and the router then the system will work again.
Because the router only goes up to the speed of 802.11b and not the 802.11g potential speed of the Airport Extreme I know that the card has to run at the slower speed when it connects with my router.
I am trying to determine whether my Airport Extreme card is defective. Any suggestions?
iBook G4 1.2 GHz Mac OS X (10.4.3)

I have updated the firmware in the router and that seems to have fixed the problem.

¿Tengo wifi 802.11n o 802.11b?

Hola, hace una semana compré el AIO C560. En las especificaciones indica:
Tipo de Wireless LAN: 802.11b, 802.11g, 802.11n
Pero el problema está en que en las propiedades del equipo no me aparece 802.11n Preamble sino 802.11b Preamble.
Tengo 200 megas de jazztel (fibra optica) y el pc está a 20 metros del router con 2 paredes por medio. Me marca 10 megas y descargando lo hace a 800kb/s.
¿Sabeis por qué me aparece 802.11b en lugar de 802.11n? ¿Si apareciese la "n" tendría más velocidad, o por lo menos más alcance (2 barritas de 5).

I think I found my answer here:
http://support.apple.com/kb/HT4199
Apple is still beyond this tech!
Routers that support 802.11n should be configured for 802.11a/n mode for maximum speed and compatibility. Routers that only support 802.11a can be left in 802.11a mode. Different Wi-Fi routers support different radio modes, so the exact setting will vary depending on the Wi-Fi router in use. In general, enable support for all modes. Devices will then automatically select the fastest commonly supported mode to communicate. Note that choosing a subset of the available modes will prevent older devices from connecting (for example, 802.11a devices will be unable to connect to a Wi-Fi router in 802.11n-only mode). In addition, choosing a subset of the available modes may cause interference with nearby legacy networks, and may cause nearby legacy devices to interfere with your network.

MacBook loses 802.11b reception

Hello,
since two days, I have a very odd problem with my macbook: after a system crash (computer fell too deep asleep while I was not watching), 802.11b (Airport non-extreme) is hardly working anymore. To be precise:
- connecting the macbook to a 802.11b basestation, or a 802.11b Computer-Computer network works only within 20 cm, and even then it drops the connection every minute
- connection to a 802.11g (Airport Extreme) network is flawless
- the networks are fine; all other computers work ok, as before
Since 802.11b also used to work fine (for a month), I narrowed the issue down to two possibilities:
- the Airport card has two antennas, maybe there's a hardware issue that would only affect the b mode?
- the Airport driver could be somehow messed up, or the card's non-volatile memory (PRAM) in a strange state
I tried installing older drivers (with Pacifist); no change. I reset all things I could imagine (PMU, PRAM, prefs etc.); no change.
Does anyone know how to reset the AIrport card itself? Or have a different idea?
thanks!
Niels
MacBook 1.8 Mac OS X (10.4.8) SMC 1.1 installed

Hi, in fact, disabling the WEP was one of the first things I tried, and for my MacBook and Lucent 802.11b (Orinoco Silver based) basestation (which is by the way compatible with Airport Admin Utility), this doesn't help at all. Security or not, inside about 15 inches of the basestation I get perfect reception (85 with 0 noise on iStumbler), further away it is just gone altogether.
When I use another 802.11b mac as virtual basestation, it's the same thing: the network isn't even seen at a meter away. When I use an Airport Extreme based computer as basestation everything is as smooth as you could want, WEP, WPA or no security at all.
I stick to my analysis that somehow the 802.11b is in a funny state on the MacBook Athereos Airport card, and I'm optimistic that some kind of software reset of the card would bring back full functionality. If only we would know how to do this, or Apple would release a patch!
thanks for all replies,

Apple TV Seems to be Synching at 802.11b speeds

Hi folks. I've been kinda frustrated with my Apple TV synching speeds (likes lots of other people apparently) and I thought I'd add my two cents.
I have a Linksys WRT54G wireless router. All of the devices on my network operate at 802.11g speeds except for my Apple TV. The Activity Monitor on my Mac Mini reports that movies are copying across to the Apple TV at a pretty consistent 1.6 MBPS. So an average 2gb movie is copying in around 20 minutes. If my math is right that 1.6 mega Bytes per second is approximately 11 mega Bits per second, which is just what the max for 802.11b is/was.
Any clues as to why by Apple TV would seem to think it's a 802.11b device rather than 802.11g. This of course is a bit speculative and yes I have ruled out interference or other weird problems. To reiterate, all of the other devices on my network, including our iPhones are operating at 802.11g speeds of 54 mbps.

Frank,
Not an attempt to debate your knowledge, and I don't even have my Apple TV yet but I have had (and currently have) different streaming boxes (Xbox 360, media player set top box [still gives me shivers], etc.) and sometimes network congestion is just a pain...
Even though everything else operates at "g" speeds, try using just the Apple TV to sync after a fresh restart with all other devices off the network...

Enable only 802.11b for a single WLAN?

I have only 802.11b client in my production environment (PLC, serial converter, ecc..).
On my WLC how can I configure a single WLAN 802.11b only and other WLAN with all-mode enable?
Regards.
Mirko S.

Sorry, there is a band 802.11g, 802.11b/g but not 802 .11b.
Is correct?
In this time I had to set the datarate 1, 2, 5.5 and 11M.
I do not think it's the right solution.

Cisco Access Point Configuration to support 802.11b & 802.11g protocol

How do i Configure access point to support both 802.11b & 802.11g clients on a Cisco 1121G series access point(AIR-AP1121G-A-K9)
Regards
Hitesh

Hi Hitesh,
Check out this excerpt from the 1121g AP Installation guide section on enabling the 802.11b and 802.11g radios.
In Cisco IOS Release 12.3(4)JA and later, the access point radios are disabled by default, and there is no default SSID. You must create an SSID and enable the radios before the access point will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points. Refer to the "Configuring Basic Security Settings" section for instructions on configuring the SSID.
In Cisco IOS Release 12.3(2)JA or earlier, the access point radio is enabled by default, and the default SSID is tsunami.
To enable the radio interfaces, follow these instructions:
Step 1 Use your web-browser to access your access point.
Step 2 When the Summary Status page displays, click Network Interfaces > Radio0-802.11B or Radio0-802.11G and the radio status page displays.
Step 3 Click Settings and the radio settings page displays
Step 4 Click Enable in the Enable Radio field.
Step 5 Click Apply.
Here is a link to the actual document:

Problem with new Time Capsule w/ 7.5 Firmware Slow Speeds on 802.11b/g

I purchased a new 1TB Time Capsule with v. 7.5 Firmware last week. This Time Capsule is replacing a first gen 500GB TC with Firmware v. 7.4.2. I have 2 Macbook Pros connecting to the new Time Capsule via 802.11n at 5Ghz and 2 iPhones and 1 first gen Mac Pro connecting to it via 802.11b/g at 2.4Ghz. The Macbook Pros connecting at 5Ghz move data fine. The connection is very fast. Speedtest.net average about 20Mbps down and 2Mbps up. The devices connecting on the 2.4Ghz radio are slow as molasses. They test at less than 30k down and 30k up. Beyond that they have trouble moving data around the LAN as well. There are no sources of major interference near the TC. In fact the TC is in the same location as the old unit which was also running at 2.4Ghz with no problems. I contacted Apple tech support and then went to a local Apple store for an exchange. They gave me another new TC but the problem persists with the new units as well. This evening I took the new Time Capsule into the basement and isolated from any kind of interference with no success. I plugged in the old TC and the 802.11g devices were back up to speed.
Has anyone had any similar issues with the new AE or Time Capsule? I'm sure it's not unheard of to get two defective units but it's not likely. So I am thinking there may be an issue with the new firmware. I tried to downgrade to 7.4.2 but the new units require 7.5. Any suggestions? All network settings are the same as they were with the previous Time Capsule. The only thing that's changed is that both the 2.4Ghz and 5Ghz radios are active.

Hi there,
got some problems with Time Capsule and 7.5 Firmware as well. Since it is my first device, I have no experience with older firmwares or models though.
It is impossible to connect to the 5GHz network. Neither when I have 5GHz and 2.4Ghz in one network or when I set a separate network for the 5GHz.
I always get a timeout message, I also tried deactivating the guest network and I also tried without any password, just would not connect to the 5GHz. By the way, I am sitting 50cm away from the TC and of course, I do have a MacBook Pro that supports 802.11n standard, a brand new MacBook Pro 13.
So, any ideas? I'm going to call Apple on Monday, can't check if it's the notebook, cause I do not have a second device to test ist. My iPhone works fine (802.11g), the 2.4Ghz also works fine with rates around 130-145 usually when close to the TC.
I also noticed that my MacBook Pro won't connect to the 802.11n when compatibility with 802.11b/g is activated. Then it runs with 802.11g instead....
pretty annoying, thought this would work right away?!

Time Capsule (SIM) expand network with 802.11b/g Airport Extreme

Hi, I try to expand a Airport-Network which is set up with a Time Capsule (SIM (latest model). I like to use an Airport-Extreme-Basestation to expand the network. The two devices will be connected wireless. In the helpfile there is a explantation how to do this with 802.11n-devices but when it comes to the 802.11b/g-devices it just says I should have a look on the apple support-pages. I do not find anything there.
I tried everything, but it did not work. I've had a Time Capsule (first model) which died some days ago (the well known powersupply problem). With this Time Capsule I did not had any problems to set up a WDS.
What to do?

try these steps provided by Tesserax:
Setting Up Time Capsule as a Second Wireless Router
802.11g AirPort Extreme Base Station -> 802.11n Time Capsule
With "mixed" AirPorts, you will need to configure both routers into a Wireless Distribution System (WDS). Your neighbor's AirPort Extreme Base Station (AEBS) will be the main and your Time Capsule (TC) will be the remote base station in this WDS.
To simplify setup, you should connect your TC directly to the AirPort's LAN port by Ethernet. Once the WDS is configured, you can disconnect the TC and place it at the desired location.
The following are the basic configuration steps to create a WDS:
(Note: To facilitate the WDS set up, jot down the AirPort IDs (MAC addresses) for each of the base stations to be used in the WDS. The AirPort ID and is printed on the label on the bottom/side of the base station.)
Main Base Station Setup - AEBS
o Click the AirPort status menu in the menu bar and choose the wireless network created by the base station you want to set up as the main base station.
o Open AirPort Utility (located in the Utilities folder in the Applications folder on a Macintosh computer, or in Start > All Programs > AirPort on a computer using Windows).
o Select the main base station, and choose Manual Setup from the Base
Station menu, or double-click the base station to open the configuration in a separate window.
o Enter the base station password if necessary. If the base station is using the
default password of public, you will not be prompted for a password.
o Click Wireless in the toolbar, and then choose “Participate in a WDS network” from the Wireless Mode pop-up menu.
o Click WDS and then choose “WDS main” from the WDS Mode pop-up menu.
o Select the “Allow wireless clients” checkbox if you want client computer to connect to this base station.
o Click the Add "+" button and enter the AirPort ID of the base station you want to connect to this base station.
o Click Update to send the new settings to the base stations in the WDS.
Remote Base Station Setup - TC
o Click the AirPort status menu in the menu bar and choose the wireless network created by the base station you want to set up as a remote base station.
o Open AirPort Utility (in the Utilities folder in the Applications folder on a Macintosh computer, or in Start > All Programs > AirPort on a computer using Windows).
o Select the remote base station, and choose Manual Setup from the Base Station menu.
o Enter the base station password, if necessary. If the base station is using the default password of public, you will not be prompted for a password.
o Enter the same network password as the main base station, if necessary.
o Click AirPort in the toolbar and click Wireless. Choose “Participate in a WDS network” from the Wireless Mode pop-up menu, and choose the same channel as the main base station from the Channel pop-up menu.
o Click WDS and choose “WDS remote” from the pop-up menu.
o Enter the AirPort ID of the main base station in the WDS Main field.
o Click Update to transfer the settings to the base station.
(ref: Pages 42-46 of "Designing AirPort Networks.)
802.11n AirPort Extreme Base Station -> 802.11n Time Capsule
o Open AirPort Utility and select the base station that will connect to the Internet.
o Choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary.
o Click AirPort in the toolbar, and then click Wireless.
o Choose “Create a wireless network” from the Wireless Mode pop-up menu, and then select the “Allow this network to be extended” checkbox.
o Next, select the base station that will extend this network, and choose Manual Setup from the Base Station menu, or double-click the base station to open its configuration in a separate window. Enter the base station password if necessary.
o Choose “Extend a wireless network” from the Wireless Mode pop-up menu, and then choose the network you want to extend from the Network Name pop-up menu.
o Enter the base station network and base station password is necessary.
o Click Update to update the base station with new network settings.
does this fix it for you ?

Intermittent connectivity, possibly due to third-party 802.11b bridge?

I use a Linksys 802.11b wireless bridge/switch/router with a 12" G4 iBook and up until recently, everything worked just fine.
Then about two weeks ago I brought home a 12" G4 PowerBook and tried to use it with this wireless network. The PowerBook is able to connect and about 50% of the time everything works fine. However occasionally I'm unable to transfer data across the network. The Wireless connection never "drops" (there is no indication that it is unavailable via the menu bar or the control panel) but once this happens I usually have to restart the computer to get things back to normal.
The time I see this the most is when I'm moving large files around on the network, either large internet downloads or just copying large files from the laptop to a NAS device I have connected to the LAN using a wired 100mbps connection.
It seems like a long time ago I had a Windows laptop with an 802.11g card and when I'd bring that up with this configuration some similar problems would occur, but that was a long time ago so I can't confirm this.
What I'm suspecting is that since the bridge is 802.11b the wireless cards in the iBook and PowerBook need to run in "b" mode. Maybe the card in the iBook does a better job of this than the PowerBook?
If my theory is correct than picking up an 802.11g bridge should do the trick, but I wanted to see if there were any other things I could try before throwing more hardware at the problem. One thought I had would be to force the wireless card in the PowerBook to use 802.11b always, but I couldn't find a way to force this configuration.
Any thoughts or assistance is appreciated!

You shouldn't have to make any changes with the Airport Admin Utility. On the Acer, just add a new network connection using the "New Connection Wizard," follow the instructions and enter your network's security password when prompted.

Photosmart C7250 wireless 802.11b fails

My new C7250 works well with USB and wired ethernet, but fails miserably (prints slowly, if at all) on my wireless 802.11b network. All other devices work well on my wireless network. I've spent many hours with HP and exhausted their first line support. They supposedly have opened a case but I have heard nothing in a week. Meanwhile, I took a network trace using WireShark and it shows a large number of retransmissions. (I'm expert with application/network performance profiling.) All you have to do is browse to http://192.168.1.xxx/ to test transmission -- don't even need to install drivers or printers to see the errors. This problem appears to be with wireless support on the C7250.
Has anyone experienced problems or success with 802.11b on this device? How about 802.11g? I would be willing to upgrade my wireless if I knew that it would resolve the problem.
What does it take to escalate a probem with HP for resolution?

All 2004 and newer wireless HP Inkjet printers are compatible with 802.11g and 802.11b networks (otherwise we couldn't get 802.11g Wi-Fi certification). Besides testing for interoperability, we test for a minimum wireless throughput at the TCP layer.
I'd like to see the internal connectivity report that you can generate by pressing the <setup> and <#> buttons simultaneously. Scan the report to a memory card, copy it to your PC and post the image here.
It will tell me information about your wireless network and other networks in the area.
I have a couple of other questions:
Does the slow printing go away after a power cycling the printer and then does it return later?
Does the slow printing go away after a power cycling the wireless-router and then does it return later?
Are you seeing retransmissions of TCP, 802.3 (ethernet) frames or 802.11 frames? I wasn't sure at what layer you are sniffing the data at?
What make and model 802.11b wireless-router are you using?
Do you have encryption enabled? Does disabling encryption change the speed of printing?
How many wireless PC's (Macs?) to you have on your network? Do they all exhibit slow printing?
Have you changed the default fragmentation settings of your wireless-router?
At home, I routinely get 1.5 Mbytes/sec transfer rates between my 802.11g wireless-routers and my HP printers and about 700 Kbytes/sec in 802.11b mode.
One other thing you can try is to go to the printers internal web page, browse over to the Networking, Wireless, Advanced page and enable the configuration "In an infrastructure network use 802.11b behavior".

802.11b vs 802.11a & g

Hi there, any one can give me some idea on the best practise about the choosing the WLAN 802.11 protocols.
I know that the in WLAN network, all device shares the same access point in half duplex, so using 11g, it would give us 45mbps to share than 11mbps (11b). therefore, I would think it is good practitice to turn off 11b on all APs, but is there any disavantage by doing so?
also on the cisco Wireless Lan Controlller web interfarce, Wireless --> 802.11a/n --> network, how to setup the DATA RATES. by default the 1 to 5.5 mbps has been disalbed. 6 to 9 mbps are mandatory, then 12 to 54 mbps supported what is the difference and impact by changing those premeter.
thanks. roy

I would think it is good practitice to turn off 11b on all APs, but is there any disavantage by doing so?
You should know what your clients before you embark in this activities. There are still some clients, such as old laptops or USB adaptors to medical equipments to brand new hand-held bar code scanners, that will read nothing but 802.11b and on 1, 2 or 5.5 Mbps data rates.
The reason why these clients are still prevalent is because of the cost to purchase these wireless cards from storage houses.

Help Enabling 802.11b Support

Can anyone help? All I want to do is enable 802.11b support on my Cisco 877W. My 802.11g clients can see and attach to it no problems. My 802.11b clients cannot see it at all. I have tried all sorts but nothing has helped. My config looks like this:

no dot11 extension aironet
bridge-group 1
bridge-group 1 spanning-disabled
What do I need to add to make it visible and available to 802.11b clients?
Many Thanks,
Matt

I'd start by defaulting the AP back to factory default, no WEP, no authentication.
Check to see if the 802.11b clients can connect.
If all the 802.11b clients are running the same software, check to see that they are up-to-date drivers & client software. If you're using the MS client software (Zero Wireless Config) try a client using the vendor's client software instead.
If the clients are not eve associating, look at the basic parameters: things like preamble length (legacy default is "long" which is a one meg data rate)
If you can get the 802.11b client to connect whith all open parameters, then add WEP. Be advised that some clients need the WEP entered as HEX, not ASCII.
For example ASCII "ABCD" would be "41 42 43 44" in hex ... make sure you're using the same system. IF youre using something like "12345abcde" that can be a valid (but incorrect) hex string when ou really intend for it to be ASCII.
Also note that leading or training spaces (ASCII 20) are valid characters. Make sure you do not have leading or training spaces in your WEP (unless you really want them there, in whch case, make sure they're there)
Make sure the Ethernet format is correct: use the Web GUI to set up. Check the parameters on the "Interfaces" page and do not (at least initially) use the "Best throughput" or "Best Range" settings, leave it at "Default Settings"
If your 802.11b clients are PDAs, bar-code scanners, or other hand-held devices, check that they are at default settings for the standard 802.11b protocols; some use proprietary protocols for better performance or security.
That's about it for me ... let us know if any of that changes (works / doesn't work, but acting differently / doesn't work, looks the same).
Good Luck

802.11n only 5GHz or 802.11b/g compatible?

Using a wireless connection to an AE, I don't notice any difference in speed and/or performance with my MB while in the "802.11n only" (5GHz) mode compared to the "802.11b/g compatible" (2.4GHz) mode. No matter which mode, I don't seem to get more than 130 MBit/s. Could someone please provide me the correct AE settings and/or tweaks necessary for me to obtain the optimum speed. FYI, my AE is connected via Ethernet to a cable modem with Charter Communications 5.2 Mb/s High Speed Internet service. (I already installed the 10.5.8 combo update with no problems)

I see you have marked this solved... but would just like to confirm. Are you using download speeds as your measurement?... or moving files within your local network? For the most part, even FiOS... which is generally the fastest internet available for the average consumer... will not saturate the bandwidth of 802.11g. You will not see any faster internet speeds using 802.11n vs. 802.11g.

Is 802.11b/g faster then 802.11g
