AP with 802.11 G Vs clients with 802.11b

hi
i've got more access point 1200 series with he 802.11g but the client are 802.11b . Can the client 802.11b connect at the AP with 802.11 G ? Now i don't resolve this problem anche the client 802.11b connect only with the ap 1200 series with 802.11b
Thanks for all

> If you disable the "b" data rates, you've pretty much blocked "b" clients.
A-ha... As i can understand i must disable 1.0, 2.0, 5.5 and 11.0 speed's.
"To set the 2.4-GHz, 802.11g radio to serve only 802.11g client devices, set any Orthogonal Frequency Division Multiplexing (OFDM) data rate (6, 9, 12, 18, 24, 36, 48, 54) to Basic."(c) Cisco IOS Software Configuration Guide for Cisco Aironet Access Points 12.3(7)JA
This the same thing as entering `speed throughput ofdm`? Command disables all 802.11B data rates as you recommend.
> They may be able to respond / attempt association (that all happens at either one or two mbps for either "b" or "g" ... long or short preambles), but since they dont have compatible data rates, they can never connect.
I know... But, AFAIK, when 802.11G AP "see" 802.11B client in his coverage area AP "downgrades" to 802.11B to allow this client associacion. Your recommedation prevents this, i'm right? Try to understand me, many years i used damn D-Link (my boss love it) but one day i sad "Cisco or on no any kind wireless :E" and now i have dosens AP-1200 with my many questions... All want now i want - is set "G-only" (in dlink's terms) like function...
Thank you
P.S. Sorry for my english

Aironet 1140N in mixed mode not working with 802.11b/g Clients

I have a new Aironet 1140N Access point , the model is number AIR-AP1142N-A-K9, my main problem in that i have Nokia E71 smartphones on the network, but they cannot connect to the Network, the Access Point SSID is not showing on the List of Available Devices if i Scan using the Phone,
All Laptops are runing Win 7 Pro and they connect quite ok, The phones (8 of them) at HotSpots connects without problems, the Spec says they are compatible with 802.11b/g and the Aironet Access point provides 802.11a/g/n.
Since the phone has the 802.11g which is compatible with the Access Point, why cant it Pick it? the Access Point is Operating in Mixed Mode.

There are basically two "flavors" of WDS that the AirPorts support: static & dynamic.
o A static WDS allows for a main, relay, and remote base stations in the configuration. This only operates in the 802.11g radio mode. Its advantage is it is well suited when you are trying to cover a considerable linear range ... like a rectangular house where the Internet connection comes in at one of the shorter sides and you want wireless at the other end. The biggest disadvantage of this type of WDS is that for every base station added, you lose half the overall bandwidth.
o A dynamic WDS allows for only a single main and multiple remotes. Think of a wheel with the main at the center and the remotes as spokes of the wheel. The advantage of this type of WDS is it operates in the 802.11n radio mode and doesn't suffer a significant bandwidth loss like the static version.
As a minimum, a dynamic WDS requires two 802.11n AirPorts (or Time Capsules). You can create a static WDS with either all 802.11g AirPorts or a mix of 802.11n & 802.11g AirPorts. Note; however, you cannot create a dynamic WDS with mixed mode base stations.

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?

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 ?

Would AX be incompatible, even for AirTunes, with a 802.11b AC?

My main router at home is a Netgear WGT624. From reading the discussions (and the user guide) I've learned that AX cannot extend my wireless network because the WGT624 doesn't support WDS.
OK, I thought, then I'll run an Ethernet cable from the Netgear router to my old iBook. It has a 802.11b original AC installed. I'll set it up as a base station. And then I'll connect the AX to that in client mode so I can at least have AirTunes.
Well, the iBook is putting out a very nice signal. But AX can't connect. Flashing amber. So is this what the AX User Guide means when it says "If your computer has +an Airport Extreme Card installed+ you can use AirTunes" (p. 18)?
And, does this mean that if I bought a refurbished 802.11g AC and put it into my other spare machine, a later eMac that takes the g card, that I could turn that into a base station and finally have AirTunes? In fact, wouldn't it mean I could extend the wireless network because the Extreme card supports WDS?
(Or should I just replace my Netgear with another AX?)

From reading the discussions (and the user guide) I've learned that AX cannot extend my wireless network because the WGT624 doesn't support WDS.
The AX can not wirelessly extend the Netgear's network but the AX can still join the Netgear's network as a wireless client. Then the AX's music streaming and printing services will be available to anyone connected to the Netgear (via wireless or Ethernet).

Stuck with a 802.11b/g router?

I have a MI424WR (Rev E) router with a 50/25 plan. This router only supports the 802.11b/g networking standards, which of course, has a theoretical wireless speed of 54Mbps, but in actuality doesn't get anywhere near those numbers due to overhead. Therefore, I'm paying for speeds I can't wirelessly obtain. I've found my way around the issue by connecting to a 2nd router which supports 802.11n, but I'm not really sure why I should have to do this. Why has Verizon supplied me with such old technology? I did some research and found this particular router began production around 2008. Is this a ploy to get people to spend more for faster speeds, or buy the "advanced" router for $100, or should I have been given a newer model modem which actually does support 802.11n?
I tried to do a chat with support, but he just wanted me to go through some pointless troubleshooting steps. I got frustrated trying to explain that my issue is hardware limitations, not router settings and ended the chat.

hlppls wrote:
Verizon bases the fact that the wired portion of the router supports your service. They still will not guarantee wireless speed so the wireless portion of the router is a just an extra feature. Turn off your router and call in saying it doesn't work. They will send you another one and chances are hight that it might be a gen 3. Even if it is a gen 3 they still will not guarantee you wireless.
Keep in mind that doing this *might* invoke a router rental fee or replacement charge on the bill, if Verizon is still doing that. He may be just be better off buying another cheap router with Wireless N or AC and either setting it up as an AP/Switch, or making the ActionTec into a backup router and take it out of the picture entirely.

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?!

Dell Axim X5 Pocket PC compatibility with Belkin 802.11b PDA card

Hello,
I was recently given a Dell Axim X5 Pocket PC and I'm trying to sync it to my IMAC using my internet connection. I'm running OS X 10.3. Dell's website stipulates that the compact flash card that I need is an 802.11b model. I purchased a Belkin 802.11b Wireless PDA Network Card to satisfy this stipulation, but upon investigation of the software I find that I need to be running at least Windows 98 with Window CE embedded. Is there anyway of me getting around this with my MAC???? To further complicate matters, when I attach the pocket pc to my USB port it isn't even recognized. Is this because it's a Windows device??? Is there any work-around for this?????
Thanks

Prakash,
Thanks for contacting National Instruments. According to hp's website, the 2490 does have a type II slot. Also, if you look at the datasheet for the CF-6004 it states that it is a Type II card. Let us know if you have anymore questions.

Just installed (not more than 15 minutes ago) an Airport card on my son's G3 iMac (running 10.4.6 I believe but didn't check) and it works just fine!! It was easy to install. I have my other son's iMac to do yet this weekened and hope it goes as well. Judy

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.

Home Hub 3, 802.11b/g/n Not Working Well With Stre...

Hi, the iPhone 4S keeps disconnecting from the HH3 when normal web browsing or streaming media on an iPhone 4S, using apps YouTube and Twitch.TV. Other symptoms is the WiFi icon flashing off and on very quickly.
This happens on 802.11n and I changed to 802.11b/g which seems to solve this. Now that Home Hub 5 is out, it looks like we are 2 versions behind?
Software version 4.7.5.1.83.8.94.1.11 (Type A)
Last Update: 18/07/13
Operating System: Ubuntu.

By using channel 5 you are overlapping with two other channels that are used by wireless routers so you could be actually making things worse. Channel 12 is better but still overlaps with 1 channel. You should look for the least congested channel on either 1,6 or 11 which are the only channels that do not overlap with other routers.

Problems with 802.11b networks

My MBP did not connect to my 802.11b home network as all my PCs do. So I upgraded to an 802.11g access point and now all the computers are talking to each other and the Internet.
But the MBP will not connect to ANY 802.11b network. I have tried several and no go!! All are unencrypted so no WEP issues. Am I missing something with the MBP or is there something wrong with the software. The configuration test window shows a strong signal and green indications for the top three lights (802.11b stuff) while turning red for the bottom three (actual connection related stuff).
I am a returning Mac user after 20 yrs with the PC, but this is very frustrating.
Thanks for your help

I've connected to 802.11b networks with no problem so it isn't a general problem.
I'm not clear on what software you are using. What software shows red and green status indicators?

D-link router DIR-615, Can't access internet with Airport Wireless 802.11B

It is a known issue with many Dlink routers that with the router wireless settings on "802.11 B,G,N" it will NOT work with your G3/ some G4 wireless cards that ONLY support 802.11B.
Enter 192.168.0.1 in your address bar to access your Dlink router. Go to settngs....wireless settings...
Go to your router settings and select "802.11B" ONLY or "802.11 B and G". This will solve the problem. D-link is aware.
I was told they will be coming out with updated firmware to correct the issue.

It's almost better to have a 2nd router for the older B cards anyway because running in multi mode with the 615, it's not a dual band device, so you won't see any speed benefits in G or N. better to run B/G anyway.

Extending home wireless network with 802.11b/g Airport Expresses

Home Setup: iMac with iSight G5 2.1GHz PPC, OS X Leopard 10.5.8, 2.5GB memory, 2 Airport expresses-802.11b/g.
Up to just recently, I was able to use my AE's to create a whole house wireless network: one as my main network connected to my cable modem, and the other as a wireless network extender. My extender got pulled out one day accidentally, and when I went to plug it in it wouldn't reconnect to my network...and so the problems began. Airport Utility used to give the option of "Extending the Wireless Network", but no more.
I've done a lot of searching through the forums regarding this issue, read through the sage advice by superusers Tesserax and Bob Timmons, and attempted to set up my main AE as my "WDS Main" AE and the other as my "WDS Remote". The WDS main connects fine to the internet, but the WDS remote continues to show a flashing amber light and inability to extend my wireless network. I've done soft and hard resets to the remote AE (which transiently gives me a green light, then back to flashing amber), network diagnostics using the Airport utility, but still no luck. The AE wireless extender continues to flash amber and is nonfunctional.
AE Wireless extender settings reported:
-WIreless Mode: Create a wireless network
-Connect using: Ethernet
AE Errors reported:
-Ethernet Unplugged
-Default Settings
I setup the AE Wireless extender as a WDS Remote, it resets and shows "Normal" without problems reported in the summary window of Airport Utility. Connection indicated as "Airport (WDS)" and Wireless Mode reads "participate in a WDS network", but the AE is still flashing amber and will not connect to the internet or Main WDS wireless network.
Went to the Genius Bar at the local mac store...they couldn't help at all.
I'm out of answers...help?!

AE 802.11n working with earlier AE 802.11b

I am running my imac and non-mac laptops through the 802.11b and have purchased the 802.11n. Is it possible to hookup the 802.11n in another room (2nd floor) and pickup a signal or is it better to use the 802.11n as the main AE and hookup the 802.11b as a secondary...

NU-Mac boy, Welcome to the discussion area!
The 802.11b base station is not an AirPort Extreme base station (AEBS). The 802.11b base stations were the graphite AirPort base station (ABS) and dual-Ethernet (aka 'snow') ABS.
Neither of the 802.11b ABSs will wirelessly extend an AirPort Extreme base station (AEBS).
