Connecting to 802.11g Projector

Just received a Hitachi CP-X2 LCD projector. All works fine when connected via video cable. I insert its wireless 802.11g card, and WiFind "sees" the unsecured device - but I cannot properly access the projector.
Where's a tutotial on establishing this type of connection with a MacBook Pro?

OK - I see
The projector needs to connect to a network (to be set up under the MIU menu / SETUP on the projector). Either turn DHCP on (if your base station is providing DHCP) or provide IP address, subnet mask and default gateway (the routers IP number). You also have to set the wireless channel (CH, normally 11) and the encryption (WEP / WPA) if any, leave the SPEED parameter at AUTO and set the NETWORK MODE to wireless; the MODE is normally infrastructure when using a base station.
The projector needs to have a valid IP configuration (and encryption settings if applicable) otherwise it cannot connect to the network. Normally the network will include a wireless router - but you can also set up the MBP to share the internet connection (when you do this the Airport antenna can not be used to connect to a router at the same time) under System Preferences - Sharing - Internet. The projector can then use the MBP as the gateway. I always use an Airport Express as it is more convenient and have not much experience with the latter set-up. Maybe somebody else can give more details here.

High Latency experienced once connected to 802.11g, but linktest results appear healthy?

I was connected at 802.11g and was running a continual ping to the DG interface on the L3 switch to which the WLC is connected too.
Response times were healthy almost all day and then they jumped very high. They continued to stay high for a long period. I disconnected (to wired) and then reconnected to the wireless and got the same results. I then disconnected for some time (connected via wired) and then reconnected via Wireless again - to which I got the same results. I stayed on the wireless connection and then it decided to come right. During this time high response time period I ran a linktest to my MAC address from the WLC and got the following results.
(Cisco Controller) >linktest 1C-65-9D-E4-55-16
Link Test to 1C-65-9D-E4-55-16.
        Link Test Packets Sent.......................... 20
        Link Test Packets Received...................... 19
        Local Signal Strength........................... -50dBm
        Local Signal to Noise Ratio..................... 44dB
Seems healthy? But yet I was getting these appalling response times. The WAP and WLC are plugged into the same L3 switch. When I connected to the wired interface my response times returned to what is expected.
I have attached the output to this discussion for review.
Any ideas as to what this would be a result of? please note that this occurred outside of peak usage hours - also note that I have seen this before another time during peak times. But no alerts or traps seen on the WCS or WLC?
Any thoughts or ideas would be appreciated.

Why put up with all that when a call to VZ will get you a replacement router?
The Westells were a good router in their day, but are now obsolete and no longer issued by VZ.

How can I tell if the connection us 802.11g or 802.11n?

G'day people
I bought a new Time Capsule today and just installed it. Both my iMac and MacBook are backing-up with Time Machine to the Time Capsule; that's great.
I also have an AppleTV and a TiVo set-top-box connected. I want to confirm that the iMac, MacBook and AppleTV are connected to the Time Capsule via 802.11n and the TiVo is connected as 802.11g.
Is there anything I can look up on both computers to confirm 802.11n connection?
Thanks
Al

Just got home from Sydney - Love it there, Mate!
Hold "option" and click the airport icon in
the toolbar. If the rate is over 54, it is n. If 54 or less it could be either, so make sure you are closer to the TC when you do it.

IPod touch 2G cannot connect to 802.11g

I'm having trouble connecting my iPod touch 2G to a local wifi network.
Up until a few months ago, I was using a Time Capsule as a wireless router for an internet connection. I could browse the internet on my iPod touch by connecting to my TC router wirelessly. But then my apartment landlord installed free wifi for all the renters, and at the same time my own internet device that was sharing the internet through the TC stopped working. Since then I have not been able to access the internet on my iPod touch.
The wifi internet is working on my iMac (very well) and MacBook Pro (fairly well, I sometimes have to move it to another room). But no matter where I go in my apartment, I cannot connect on my iPod touch. In my room I cannot see the wifi network at all; in other rooms it appears momentarily, usually with 2 out of 3 bars on its signal strength icon, but whenever I try to connect I usually get an error that says "Failed to join... (the network)", and occasionally I get a pop-up error that says something like "Unable to join... (the network" and it has a big "Dismiss" button.
The iPod touch can grab wifi with seemingly no problem at other locations, such as my workplace, my church, businesses in town, etc.
An app on my iMac called iStumbler reports that my home network is 802.11g. I believe this should be supported on my iPod touch? If so, I cannot figure out why it is not working at home.
Is it most likely that its antenna is going bad? Or the signal is too weak (it shouldn't be, the signal source is right next to my apartment building, and my iMac shows a strong signal)? Or could it be some kind of software/hardware setting that I should get my landlord to look at or tweak?
I'm a bit frustrated!

I did all like you said. After that i have seen that my ipod touch isn't supporting 40mhz mode so i changed it to 20 Mhz and i put B+G band because my ipod is not supporting B+G+N mode. Nothing, i cannot connect. On my other 2 routers i can connect but...my other two are not mine
I did some screenshots of my router's configuration. If is something to change please help me!

Xbox 360 Wireless N Adapter Only Connects to 802.11G on WRT310N

I recently purchased the Xbox 360 Wireless N Adapter. I plugged it into my Xbox (which is current on updates, including the adapter drivers), and am able to successfully connect to my WRT310Nv1 using the "Mixed" mode, but only at 802.11G, not 802.11N. If I force my router into "Wireless-N Only" mode, the Xbox is able to see the signal, but will not connect. The WRT310Nv1 has the most recent firmware (v1.0.09) installed, and I am using WPA2 Personal, AES encryption.
I've scoured the internet and haven't been able to find a solution yet. Any help or suggestions would be greatly appreciated.
Thanks!

I have an Xbox 360 Slim with the built-in Wireless N and I have the EXACT same problem. I also tried forcing my router into Wireless-N only mode and the Xbox will not connect. It will only connect in "mixed" mode but at 802.11G. This is very frustrating.
If any one can help us out it would be much appreciated!!

Satellite Pro M10 Model PS630E. Connecting via 802.11G

This laptop has a 1.5 Gb Centrino Processor,is there any way to upgrade the wireless so it can detect 802.11g wireless routers as it seems only to see 802.11b. Is there a driver update or more up to date firmware.

Hi
I think the easiest solution would be a usage of external USB WLan stick which would support the WLan 802.11 G standard.
The USB WLan stick is easy to use, cheap and you dont need to disassemble the notebook in order to upgrade the WLan card.
Visit some online dealersIm sure you will get nice one for some bugs

S8-50 Tablet connects only to 802.11g networks not 802.11n

My S8-50 table will only connect at 802.11g speeds to any wi-fi network. I tested this with multiple routers and the tablet will not connect at all if the router is set to 802.11n only mode. The wi-fi networks were using WPA2 AES/CCMP at the authentication method. The S8-50 wi-if adapter is listed as 802.11bgn so it should connect at 11n. Has anyone else run into this issue and is there a way to fix it?

If you are referring to the fact that it's not connecting to a 5GHz network it won't as the WiFi module is not a DUAL one ... It will connect to bgn networks but only in 2.4 GHz band.

Time Capsule slow as 802.11g WAP

I've been having trouble with my wireless network since I received my 1TB Time Capsule. AppleTV quit syncing, .Mac Sync hung repeatedly, and Printing via the Time Capsule stutters. I only have 802.11g hosts on my network, so 802.11n performance isn't something I'm evaluating.
The goal of this testing is to assess the Time Capsule as a network access point for 802.11g hosts. Disk read/write is not part of this experiment. Each of the measurements below are results from the exact same test -- measure internet upload and download performance to a test server on the speedtest.net network.
My topology is as follows:
SBC DSL -> 2Wire modem -> TimeCapsule
For the tests below, I connected my MacBook Pro to each device, wirelessly via 802.11g and direct connect via Ethernet and ran the test from speedtest.net. Since I have a 3Mb connection, the speed of my ethernet is irrelevant. The results of the testing is below and the results show that using the Time Capsule as an 802.11g hub is slow, in fact 75% slower.
Internet Performance (3Mb service)
network performance -- connecting via
*660k dl/430 ul -- TimeCapsule (802.11g - single base station, or as WDS main)*
2546k dl/429 ul -- TimeCapsule (Ethernet Hard Wired)
2547 dl/432 ul -- 2Wire 802.11g
2546 dl/431 ul -- 2Wire (Ethernet Hard Wired)
My conclusion, based on this testing and from several posts in this discussion board is that the Time Capsule exhibits poor performance for hosts connecting via 802.11g.
Is there some setup thing I'm missing?

The initial backup should have been wired. Future incremental backups would not be this large and wireless backups should be okay.

Airport Extreme 802.11n (with gigabit ports) locks up when using 802.11g

About a minute after I connect my 802.11g IBM X60 laptop to the wireless network, the AirPort Extreme with 7.2.1 firmware locks up. The light stays green, but all machines (including an 802.11n MacBook) loose wireless connectivity. It's extremely annoying and makes the base station unusable. I have to physically disconnect it from the wall and plug it back in for it to work again.
Has anyone found a fix for this?
It works fine when a single 802.11n Macbook is connected.

Changing it to 5Mhz didn't help. I unplugged my external HD from the router. Want to try to figure out what made it start locking up because it didn't do it when I got it two weeks ago, just started yesterday.
But I might be going to a mall where an apple store is, might just have them swap it out. It's hard to prove this type of thing, unless it's a known problem and they take your word for it.

Airport Extreme 802.11g base station loses internet connection often

I just installed an Airport Extreme base station (802.11g version Apple Base Station V5.7) last week. And it keeps dropping my internet connection at least once a day.
I simply replaced an old SMC Barricade wireless router that died (and was a POS). But I only had to reset the SMC about once every 2 months. Nothing else has changed in my setup. Only the router/base station is different.
The wireless part is fine. Even when the internet connection gets dropped the hard wired AND wireless clients can still access the local network. Reseting the DSL modem has no effect. The only solution is to power cycle (unplug and plug back in) the AEBS OR restart it from Airport Admin utility.
But you can't do that from offsite. When the AEBS drops the internet connection I can't access my office network from home!
Is there a place in Airport Admin Utility which tells you the status of your internet connection like most generic wireless routers with web-based software do?
Any ideas on resolving this?
Thanks

"Any ideas on resolving this?"
Looter,
Based on your description, open AirPort Admin Utility and check the configuration of your main base station on the "Internet" pane. If you're using ethernet cable from the modem to the base station, the top selector [Connect Using:] should show "Ethernet" and the second selector [Configure:] should show "Using DHCP"
Also, check your iMac's System Preferences>Network at "Show: AirPort" and check the PPPoE pane which should show no entries (unless your isp requires its use), and the TCP/IP pane which should show "Configure IPv4:" as being "Using DHCP" - while all other info is filled in automatically.
"Is there a place in Airport Admin Utility which tells you the status of your internet connection like most generic wireless routers with web-based software do?"
No, the AirPort Admin Utility is not web-based, only located on your computer with the information available to it necessary to operate the AirPort system. It does not actually administer the signal. I think that is done only by System Preferences>Network.
"I'm actually referring to the Airport Express base station not my MacBook Pro's wireless connection. Is there anywhere in the Airport Admin Utility software that tells you the status of the AEBS' internet connection NOT the wireless connection."
No, that info is not available in that utility. The information you seek is at System Preferences>Network, but only after the system scans for it. Click the "Assist me..." button and then, on the "Do you need assistance setting up a new network connection or solving a network problem?" panel that opens, click the "Diagnostics..." button. A "Network Diagnostics" panel will then open and if its scan shows there is no internet the lights to the left of "Internet" and "Server" will be yellow instead of green. Meanwhile, it continues scanning for the connection until it is re-established. I determined this by pulling my cable from the phone jack, later reinserting it.
Further information that may be helpful to you can undoubtedly be found in threads such as this other one:
http://discussions.apple.com/thread.jspa?threadID=884049&tstart=0
edit-
In re-reading, I may not have given you what you need. It sounds as if you may be "timing out" somehow on your connection. You might want to check around at some of your log-on settings to see if there is that possibility connected to one of them, even though the only thing I can think of is the "Renew DHCP Lease" button which is unknown to me, as I've never used it.

I would like to replace my old AE 802.11g with new version 802./11n - How do I connect

I have just bought a new Airport Express (802.11n wi-fi) and would like to use it as the base station in place of the older version (802.11g).
The old one to be used in another room connecting to my sound sytem as an extention to the new one.
Both of these AEs utilise different Aiport Utility (5.6 against 6.1).
Can anyone please give me some detailed explanations of how I can set-up these devices, if indeed they are possible.
Alan

Sorry, just to make sure: Do you want the older 802.11g Express just for iTunes streaming or (in addition) to extend the wireless range of the newer 802.11n Express? If it is the latter, you may want to reconsider doing so as the only way to extend with "mixed" base stations is with a Wireless Distribution System (WDS).
A WDS has two major disadvantages: 1) It can only operate in the 802.11g radio mode, basically negating the advantage of your 802.11n Express, and 2) For every base station added to the WDS, the overall bandwidth is cut in half. So starting with 54 Mbps (for 802.11g), your extended wireless network will be running around 25-27 Mbps.

Why won't my iPad 2 connect to my 802.11g network?

Hello everyone,
Today I received an iPad 2 as a gift. It is the first Apple product I have ever owned. I spent about 3 hours this morning trying to get it to turn on -- it kept displaying an image of a USB cord so I connected it to my computer. Still the iPad would not display its desktop. Finally, I learned that the iPad had to be connected to a PC running Windows (instead of the Centos 5 Linux system that I use). Additionally iTunes had to be installed. I find it extremely bizaare to require the device to connect to a computer before being able to turn it on.
Now after getting the device to boot, I am attempting to connect to my home wireless network. Thus far it appears this is going to be Strike Two for me and the iPad 2. My wifi network is 802.11g using WPA2-AES and 128 bit key. The iPad 2 recognizes the presence of my network (the SSID appears in the listing when it prompts me to connect), however, when I supply the 128bit key to connect, the iPad 2 reports that it is unable to connect.
I went into the Network configuration in the General Settings and attempted to add the network manually (ensuring I could specify WPA2 as the encryption type). Same failure.
Any hints on getting this thing to connect to my network? I've already watered the security down to 128bit encryption (from 256bit). All the other devices in my home are able to connect without issue. The iPad 2 detects a strong signal from the router.
Thanks,
Josh

I appreciate everyone that responded with the intent of helping me solve the issue. This forum is weird -- there are many users that try to help with iPad2 issues and then there are many that mock me and say I should just return it for expecting this very expensive device to just work.
After a late night of debugging with Wireshark, I finally tracked down the problem (Apple, feel free to send me a cheque for my services)
I will post the solution here for those who desire to use an 802.11x security protocol that has not yet been compromised (WPA2-AES).
When you attempt to join a wireless network, the iPad asks for the password. If this password contains any characters other than 0-9, A-F (hexadecimal), WPA states that Password Based Key Derivation Function 2 (RSA Security, PKCS #5) must be used to calculate the pre-shared key. If however, the password contains only hexadecimal characters, then that value *is* the key to be used (e.g. do not run the PBKDF2 function)
I specify my network keys in hex both in my router and my devices. This means the devices nor the router need to invoke PBKDF2.
The key I specified in my router was entered using upper case hexadecimal letters (e.g. A, B, C, D, E, F) whereas the key I entered on the iPad 2 was entered using lower case hexadecimal letters (e.g. a, b, c, d, e, f). Since I am specifying a key, the uppercase and lower case hexadecimal values have the same binary represention -- meaning they are identical. The iPad, however, does not treat them as identical and therefore attemps to connect using an invalid pre-shared key (my guess is it is running PBKDF2 when it shouldn't be -- but I don't care enough to troubleshoot it any further)
In summary, this issue will only affect those of us that specify our pre-shared keys explicitly (via hexadecimal) in the router. As a workaround, make sure you enter the hexadecimal key using only lower case letters (a-f) when you set the key in the router and use lower case letters (default) when entering the key on the iPad 2.
After doing so, iPad 2 can connect as can the other 20 devices I own that followed the WPA specification in the first place.

Connecting TC to a 802.11g network

I have an internet connection already set up, and I want to connect my new TC to it. However, whenever I try to connect it wirelessly, it does not connect, and I have to restore the TC's factory defaults. I think this might be because the current network is only 'g' standard. Is this possibly correct, and if so, how can I change the TC settings to operate on 'g' standard (as it is compatible according to specs)?
Thanks!

Yes, you will want to run AirPort Utility and select Extend a Wireless Network as your wireless option and will run in the same wireless mode as the device it is extending (which I'm assuming is 802.11g from your information).

Airport Express 802.11g cannot connect with OS X 10.8.3

Hi just updated my MacBook Pro to OS X to 10.8.3. I have an older model Airport Express (802.11g) that I have been able use to set up wireless speakers via Airport Utility 5.6 and 5.6.1. However, this most recent Mountain Lion update has rendered my Airport Express useless. I have to restart Airport Express each time I want to try to use it, to which Airport Utility will find the device and successfully add it to my existing wifi to allow me to play music wirelessly through my speakers. The second I close my MacBook, though, everything disconnects and Airport Utility is no longer able to find my device. The green light is steady on the Airport Express, so I know that is hooked up and working correctly. Is there a fix for this....? Thank you!

See if setting a static IP will correct the problem. Step 5 in the document below will walk you through the steps. Let me know what happens.
