Questions About WiFi Interference

I'm having connectivity issues. I upgraded to an 'n' router about 3-4 mos. ago (a Belkin N300) and was experiencing intermittent connectivity with my MBP and iBook G4, while my work computer (Windows) has had no issues.
Switching to channel 11 seemed to take care of it for a couple of months, but the issue came back about 2 weeks ago. I've read through the support article about troubleshooting interference issues. And yet, it seems odd that the Windows machines are running without a hitch. So here are my questions:
Is it common for channel interference to impact computers/ OS differently or is there something else going on?
Short of switching to a dual band router, like the AEBS, is there something else I could/ shoud do to fix this problem?
(Assuming I need to get a dual-band router, any recommendations are appreciated.)
Thanks

Much obliged, Aussie.
Well, I'd say yes to that. Based on the fact that they might be in different locations physically, therefore be closer / further away from the interference.
We do have cordless - one about 8 ft. away from where the MBP usually sits -but I've used the PCs in the same space and the close proximity of the phoneshas never been an issue for them (not to beat a dead horse).
And for what it's worth, I've not noticed any correlation between theconnectivity issues and where the computer is sitting. Right now I'm sitting roughly20' away from the phone and still having connection issues where it will completely drop the connection and then comes back on its own after several minutes. I think the onlyother potential source of interference in this room is an old WinXP desktop that we hardly ever turn on.
So if it's not dual-band, I'm presuming that you have it set to 'n compatible, so it will slow down to g if some g device connects to it? Force it onto n.
Right now I have the router set to compatibility with b, g & n though the only 'g' computer we have in the house is my old iBook G4, which is rarely connected, much less used. Taking your advice would require getting a new 'n' adapter for the iBook, right? That is, unless I upgraded to a dual-band.
And I'll just have a guess and say that you have cordless phones lying around the house. Remove them. Isolate anything outputting frequency.
Doing away with the cordless phones doesn't seem likely to go over too well, so will probably upgrade to a dual band router.
Once again, thanks for your guidance.

A dumb question about wifi...

I'm not as 'literate' as some are when it comes to computer technology...but here is the question...If I walk into a place that has wifi and my iphone is set with wifi ON, how will I know if there is a charge for using the wifi? Will my iphone automatically kick into the wifi or will there appear an invitation to pay a fee to connect...and how do you pay and do you have to have a password and if so, how do you get that? I know....dumb question...Thanks.

Not a dumb question at all.
First of all, set your iPhone up like this:
1) Go to Settings on the main screen (looks like gears)
2) Click on "Wi-Fi" (second option from the top)
3) At the bottom of this page (Which should say "Wi-Fi Networks" at the top) turn "Ask to Join Networks" to the "ON" position.
Now when you walk into a place that has Wi-Fi, your iPhone will display a little window that asks you whether you want to join the network or not.
In some places, you may even see a list of more than one Wi-Fi network to join. This is quite common in New York City. The reason is because so many people have Wi-Fi in there apartments, and they all live so close together, that sometime your iPhone can detect multiple networks. The coffee shop near my apartment has their own network, but I can also connect to the Wi-Fi network in my apartment because I only live about 50 feet away.
Anyway, when you see the list of Networks to join, you may notice a little padlock symbol next to some of them. This means these are closed networks that require a password to connect to. (My network is "Closed", ie requires a password so that everyone in the coffee shop next door doesn't use my internet).
Networks that DO NOT have the little lock symbol are "Open" which means you can join them without a password. But there is a catch... A lot of coffee shops have open networks, but as soon as you try to browse the web, they redirect your browser to their own page, no matter what web address you enter. Basically, they are letting you connect to their network without a password, but not letting you browse the internet without giving them some money.
So (as the previous poster said) the page that the coffee shops redirects you to, usually has instructions, and of course a place to put in a credit card. Once you do all that, then you can browse the internet without getting redirected to their little payment page. Its sort of confusing because you don't need a password to connect to their "open" network, but you do need one to browse any web pages. How you get the password differs from coffee shop to coffee shop, but usually they give it to you right inside your web browser once you give them your credit card number.
T-Mobile provides wireless for Starbucks (at least in a lot of places they do). So once you have an account with t-mobile, you can use it in any starbucks or "T-mobile hotspot"
Now this all sounds kind of complicated, but more and more these days, you can just walk into a place, find an open network (one without a lock next to it) and start browsing without being redirected or dealing with credit cards. Basically these places are providing free internet to try to attract customers.
Good luck
P.S. Wi-Fi eats up battery life. If you aren't going to be using it to browse web pages, you can go into settings, then Wi-Fi, and turn Wi-Fi off. This will save you battery life, but you have to remember to turn it back on. Even without Wi-Fi on, you can still browse the internet if you see a little "E" at the top of your screen. The E stands for the AT&Ts Edge network, which isn't as fast as Wi-Fi, but covers pretty much everywhere that your phone can get a signal.

Game Center Question about WiFi

Does anyone know if you can play games with someone connected to the same WiFi as you? I've read about port forwarding requirements and that seems to indicate you cannot since you can't forward a port to multiple IPs.
I have tried to paly a game with another ipod in the house and game requests never reach either IPOD.

Make sure that there is a tick next to your wifi network of choice. This is under Settings>Wi-Fi>
If there is no tick the Wi-Fi will be on but not connected.

Question about WiFi with a Satellite Pro 4200

Has anyone already connect a wifi card on a Satellite Pro (W98)? Please let me know type of PCMCIA, etc ... Alternatively wired connection to Lan.
Thanks

Hi
As far as I know you can use any types of PCMCIA WiFi card on your unit.
Sometimes you have to install the drivers or any Utilities from the PCMICIA Wireless card manufacturers. Please check some websites in Google. There you can find many attractive offers for WiFi cards.
Best regards

A(nother) question about wifi.

When I go to my wifi connection, then the blue arrow, under the DHCP heading, right down the bottom, there's a button that says 'renew lease'.
What is it for? I really want to press it but I don't think I should.

A device such as an iPod touch or computer receives an IP address from a router for a specified period, which is referred to as a lease. Pushing that button causes the duration of that lease to be extended; it will normally happen when the lease is close to expiry. Pushing that button probably won't have any effect.

Questions about Wifi

Where I'm at (until they get the cell tower fixed, it was hit by a tornado) cell service is poor. On a good day, I might have 3 bars but it usually hovers around 1 bar. Makes browsing really slow. Now this might be my imagination (please tell me if it is) but when I turn my wifi on (I have dsl with a router and have set my phone up for it) browsing speed goes faster so I'm assuming I'm browsing on wifi rather than network connections. (I also do have a data plan) Am I correct in assuming all of this?
That being said, when I leave home and I know there is no wifi available I try to remember to turn the wifi off because I'm afraid if my phone is looking for a wifi connection, it will be hard on the battery. Am I correct in this assumption?
I might have this phone figured out in a lifetime or so. Tell you what, technology needs to slow down. My old brain can't keep up.
Solved!

grammy, I believe you are correct!

Before I buy an iPad...a question about Wi-Fi

Hello.
I have a question about WiFi and iPad use.
I am dependent upon Internet access as I am disabled and do all of my shopping and billpaying from home.
I recently had my computer PRAM go bad and became aware that I need a back-up method of accessing the Internet should my iMac go on the fritz again.
I have decided to buy an iPad - but I am not knowledgable about WiFi. I have Internet through Road RTunner via cable and an Ethernet connection, but I doubt there is a local WiFi hot spot available that covers my home.
What method should I use to obtain a home WiFi connection that I can use for my iPad should my computer not be available? Would AirPort fulfill this need? (I do not know if my computer has to be running to use AirPOrt).
IN any event, can anyone offer any advice? Thanks!

An AirPort router should fit this need well- and your computer does not need to be running for it to work. However you do need a running computer to set up the AirPort. Depending on the size of your house, you could get either and Airport Express (for a smaller house) or an Airport Extreme (for a larger house). You could also look at a website such as Best Buy's and buy a router from a different company; Apple routers tend to be more expensive than others. The main advantage of buying an Apple router is that they are usually much easier to set up.
In short, what wifi in your house would do is take your home internet connection and broadcast it wirelessly.

Question about personal hotspot. I know I can share GSM / 3G but I would like to know if my iPhone is connected to a wifi can I also share that wifi collection, through personal hotspot?

Question about personal hotspot. I know I can share GSM / 3G but I would like to know if my iPhone is connected to a wifi can I also share that wifi collection, through personal hotspot? And if so can it be through wifi or does it have to be Bluetooth or USB?
Sounds like an odd question but my phone will connect to BT Openzone so I want to share that with my iPad via personal hotspot. I could use 3G but then it comes off my data allowance and I don't want to have to buy a separate SIM for my iPad if I can avoid it. I can swap my sim from my phone, but that's a pain!
Thanks
Luke

No, unfortunately Personal Hotspot will only use your 3G plan.

Question About Sharing Apps Between My iPhone and My Wife's iPhone

Hi, I have a question about downloading apps to my iPhone.
I ordered two iPhone 3g's - one for my wife and one for me, and I've discovered that when I download an app (even free ones) on my iPhone and then later sync it to iTunes, my wife cannot put it on her phone. However if I download it on iTunes on my computer and later sync it to my phone, then my wife is able to sync it to her phone as well. It's no big deal when they are free because she can just go get it if she wants it. I haven't purchased any apps yet, but is there a way to be able to give my wife apps that I purchase on my iPhone? Or do I need to purchase all of my [pay] apps and songs on iTunes on my computer to ensure we both have access? Or do I have it all wrong completely LOL?? This rights management stuff is confusing.
Thanks in advance for your help,
Jimmy

I had my iTunes account and phone before I got my wife's hers. When I first started, I synced hers from her account on my computer brought in my libraries and authorized her phone as one of the 5 allowed. She had all purchased apps and music. Over time we each bought music or apps on our seperate accouts. Of course, we told each other about cool apps or music we bought and wanted on our phone. When I went to sync iTunes was going to delete all music and apps and sync with the library I was logged into. Didn't want that, only work around I have found is to copy new music or new apps from one library to the other. Updating on the phone is also difficult because you can't switch between accounts so updates have to be done at the computer for apps bought under different accounts. I am sure there is a better way to do this and ask for an insight anyone would have. I hope it works out.

A lot of questions about my MacBook Air

I am really new to re-using Apple computers.The last time I used an Apple computer was back in 1987 when the school and my family had Apple IIGS computers. I have been using PC's which reqiure Microsoft. I a lot of have questions (10 questions) about my MacBook Air and I hope you good people can and will help me.
Product: MacBook Air
Operating System: Mac OS X Version 10.7.4
1) I Downloaded MacKeeper because I was fooled. I had a bad feeling just before I Downloaded it and I should have listened to my heart. However, I didn't buy it or fully Install it. It was like a test run and then they wanted me to pay almost $100 for it. Thankfully, I didn't because I read it is Malware. I spoke with an Apple Tech at Apple Care and he helped me get rid of it (or so we think). I don't see it anymore on my computer. I read it can slow down your computer. How can you tell if it's really off of the computer?
2) When I open "Finder" and I see that there are people Sharing my computer with me. I went into AirDrop and it reads, "Other people can see your Mac as (my name) MacBook Air when their computer is nearby." I bought a HotSpot and while it's turned on and I selected it as my WI-FI connection I thought it would get rid of these people, protect what I type, me, my items, computer, etc. But it didn't.
I didn't know that I have to buy a exteral CD and/or DVD Player in order to connect to the brand new Modem and Router in one by NetGear. I am so used to PCs and the CD/DVD Players being built inside.
The people at Apple Store told me that there is an internal modem inside, but I don't know how to find it and what to do then. Should I use a Firewall?, An AntiVirus, AntiMalware, AntiSpyware, etc. Apple Care tech told me I don't need to get an AntiVirus.
3) Is there a new kind of Wireless Modem and Router that doesn't require a CD-ROM?
4) When I travel or fly and I am not close to home I was told by Best Buy and Sprint that I had to buy a mobile HotSpot to use the computer (WI-FI) safely. As I typed, I have one. But it's pretty expensive and only gives me 1 hour and 15 minutes per day to Stream. What can I do to use this computer safely Online when I am out of range from a Modem and Router? What do people do when they travel on airplanes?
5) This compter won't let me use "Raid." I think you have to have a newer version. I hard about Raid on the radio from Leo (can't recall his last name) who's a Tech expert.
6) Should I buy a ZipDrive? Apple Store Tech told me that I didn't need a ZipDrive. I just remember the episode of HBO's "Sex and The City" when Carrie looses everything because her copy crashed. Now, of course, I know that's a fictional show, but with PC's and Microsoft I have lost everything when it crashed, frooze up, etc. I know there's iClouds. I heard about Carbonite, but I have read the Pros and Cons about it. Mostly they are Cons about it. I just don't want to do anything wrong and mess up this computer.
7) Should I buy a new Printer/Copier/Scanner because mine is an HP. It's not new, but it works. I even have a CD-ROM for Macs. What about the new product called, "Neat"?
8) Is there a special product that I should buy to do Online Banking and/or other important stuff?
9) I saw and read about iWork in the Apps Store and it sounds cool. I still have alot of friends and colleagues who still use Microsoft. Is iWork good to use? Should I Download it from the Apple Apps Store or can a buy it at Apple? Is there another Word Processing Program that is great and user friendly and will work with Macs and PCs?
10) Should I Update the OS with OS X Mountian Lion Pro from the Apple Apps Store or buy it at Apple Store?
In advance, I wish to thank you in this Apple Support Communites for your help. Have a safe and happy holiday weekend!

1) Here are instructions for removing MacKeeper. Since it mostly consists of manually looking for folders and specific files, if you follow the instructions you either fail to find what you are told to find (because your AppleCare guide gave you complete instructions which you followed) or you'll find some additional files that need to be replaced.
2 & 3) I assume you are looking at the sidebar of a Finder window and seeing Shared and computers under it. Those are computers that you can potentionally share. To do so you'd need an account on their computer and a password. They are not sharing your computer.
AirDrop allows you to create an adhoc network for filesharing and it only functions when you have selected the AirDop item in the SideBar. Actually doing that merely announces to computers in the same network node that your computer is available for a file to be sent to. Even then you have to explicitly allow the file to be downloaded to your computer. Similarly you'd be able to see other computers with AirDrop selected and be able to send them a file - which they'd have to accept.
The only reason your NetGear Router comes with a CD is to install and run their 'easy' step by step configuration program. It can also be done manually with a browser. Read the manual to find the IP address you must enter to access the router's configuration menu. Apple's WiFi routers don't require a CD to install the software because the configuration software is already on your computer.
I do have my firewall turned on. AntiVirus software isn't a bad idea - I use Sophos having tested it for a review for our local User Group and I found I liked it better than ClamAVx which is what I'd been using before. Both are free.
4) I think you were scammed by Sprint and BestBuy. I use hotel, coffee shop, and restaurant WiFi spots and have for years. However, because they can be unsecured, I do not shop online or bank when I'm using them. I also use 1Password and don't reuse passwords so even if a sniffer should grab an account and password that's all it would get - one account.
5) Raid doesn't really make sense with a MacBook Air - a RAID involves 2 or more disks being used as if they were one.
6) Zip drive? No. External hard drive - yes. It isn't a question of if a computer's hard drive will malfunction, it is when. OWC has a nice selection of external drives and the Mac has a built in backup system called TimeMachine. Due to the way TimeMachine works, I've found that your TimeMachine drive should be at least twice as large - and preferably 3-4 times as large as the data you are backing up.
7) if your printer works and it has Mountain Lion drivers, why replace it?
8) Online banking is done with a browser - Use Safari or FireFox
9) If trading files with Windows users is important Mac: Office is your best bet. If not, iWork, Mac:Office, or LibreOffice are all good possibilities.
10) you can only buy Mt Lion via the App Store.

Some questions about a Time Capsule

Hi!!
I just have a few questions about a Time Capsule, but first let me explain the backgroud to my questions.
I live in a 2 floor house(including a basement) and my bedroom is downstairs. My parents currently have a desktop PC connected to our wireless router and our printer. Me and my step-father both have 13 inch MacBook Pros, and he uses the Mac like a basic computer, so the equipment connected to our PC is good for him. I, on the other hand, use my Mac, iPad and iPhone to their fullest potential. I am a SUPER MEGA NERD when it comes to computers, so I plan on making my bedroom an amazing office at the same time. So I want an AirPrint Enabled printer in my bedroom (Under 100$$) along with a Time Capsule to back up my information, because everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
If you don't understand what I'm trying to ask (Even though I feel like it's self-explanatory)
ONE question about the PRINTER: Do any of you have any recommendations for an AirPrint Enabled printer under 100$? Even under-150$ would be okay.
THANKS FOR ANY HELP!!!!

everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
Don't just depend on TM.. use a disk image type utility.. either one of the Mac tools, SuperDuper, CCC, Chronosync or even a linux boot cd (if you have a cd/dvd drive still or via usb can boot) a great tool is Clonezilla.. it will do basically any computer, Mac, Linux, Windows.. and since it boots into its own OS can restore a computer in a flash. Then you can add the incremental changes from TM.
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
Actually I am surprised you get good wireless as usually directly above or below a router is often the worst spot. Time Capsule cannot extend the wireless of any other router than Apple.. it is a special system and only Apple can join the club. It has bad effect though, if you set the TC to extend wireless it turns off ethernet ports.. which is hugely dumb.
The best arrangement is ethernet to the upstairs.. or EOP adapters. If not then a wireless router that matches the existing unit will generally be better than mixing apple and non-apple.
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
You create a new wireless network by selecting manually the wireless channel and use different wireless name, ssid and security. There are 3 available channels on 2.4ghz.. your existing router will use one or two.. depending on if the setting is 20mhz or 40mhz.. so you need to manually set everything and not use auto.
TC is slow on 2.4ghz cf 5ghz and there are many more channels at 5ghz but not everything can use it.. iphone for instance is 2.4ghz only . whereas ipad can use 5ghz.. most full computers now can use 5ghz.
Buy a wireless network printer. Or alternatively an ethernet network would be also ok but now are more expensive than wireless ones. Network printers are not much more than straight USB and work much better.
I do not use airprint so have nothing to offer.. find the best HP model in your budget.. but others may have had more experience.. I use ethernet connected b/w laser business type HP.. they work great.. but airprint is too recent an innovation for me.

A question about grub and USB

Hi All
I have a quick question about grub and USB that I can't quite find the answer to by searching. Most of the FAQs discuss booting a full linux dristribution from USB. My situation is this. I am getting a new computer with two drives, the second will be arch and the first will be Vista (for my wife). I want the computer to boot the same way that my wife's machine boots at work so I don't want to install grub on the MBR. So, is there a way to have all of the grub config files and kernels installed on the second drive and simply install to grub boot loader to the MBR of a USB stick? My goal would be to simply plug the USB stick into the new PC and boot arch from the second drive.
Thanks
Kev

i cant say for hp's
havent worked on any in a while
recent machines have been coupleof dell's , vaio & emachine
which dells do offer it at least the ones i tried , my laptop does(dell)
all home pc's are built by me which do offer to boot individual drives
what hp you getting it may tell in specs
are both discs sata? if so it might not offer this option with 2 drives of same interface
check your power supply alot of these preconfigured machines put cheap under reated power supplies in there
& will burn your motherboard i just replaced PS(250 watt) & mobo(845gvsr) in an emachines <cheap stuff<
i hope you researched the pc before buying ie : mobo, power supply are the biggest concerns
i find it much more benificial to build my own machine gives me peace at mind. the cost is sometimes more in $ but not always , your biggest expense is time researching hardware
if you live in usa the best places to start looking are bensbargains.net & pricewatch.com
i am not affiliated with either & niether sell the hardware they are just advertisers a place to buy
for costomized machines that i would trust is unitedmicro.com theyll asemble & test before shipping
i have gotten 2 machines so far from them with NO PROBLEMS with hardware (knock knock)
you may want to consider this in your next venture for pc

QUICK QUESTION ABOUT PORTS

Hi, I have a quick question about port forwarding/mapping. My question, lets say I am running MSN messenger, who's ports are 6880-6900. But lets say I am running a torrent application or something else that requires those ports. If both applications were running at the same time, would this cause interference with them on the same ports or now. Thanks
Nathan

Normally, only one application can listen to a specific port number at a time. If MSN is grabbing those 21 ports then your torrent app won't be able to run.
However, most apps don't work that way - even if they use multiple ports, they don't use them all at the same time, so MSN might use 6880 when it starts up, leaving the others open for other applications to use if needed.
Only experimentation will answer that one.

Good afternoon! I addressed in the AT&T company with a question about untying of a sim card of AT&T from my iPhone, all of them made Iphone now is unlocked, I executed all points which were written:
To complete the unlock, simply
1 . Open iTunes on your Mac or PC and verify that you have Internet connectivity.
2 . Ensure a SIM card is inserted into your iPhone.
3 . Connect your iPhone using the dock connector to USB cable that came with your iPhone.
4 . Backup and restore your iPhone using iTunes. For information on backup and restore, please visit http://support.apple.com/kb/HT1414.
5 . After restoring, your iPhone will be unlocked.
Additional information on unlocking can be found at http://support.apple.com/kb/TS3198
I made everything as well as was written, but on completion of the ios 6.1.3 installation the iPhone asks to be activated through wifi or through a wire to the computer.
I connected Iphone to the computer and the text takes off: (Were sorry, we are unable to continue with your activation at this time. Please TR again later, or contact customer care! )
how to me to activate my iPhone?
I hope for your help....

Hey APPLELovestory,
We have an article that goes over troubleshooting iPhone activation issues here:
iPhone: Troubleshooting activation issues
http://support.apple.com/kb/TS3424
Perform the following steps:
Restart the iPhone.
Try another means of reaching the activation server and attempt to activate.
Try connecting to Wi-Fi if you're unable to activate using a cellular data connection.
Try connecting to iTunes if you're unable to activate using Wi-Fi.
Restore the iPhone.
If you receive an alert message when you attempt to activate your iPhone, try to place the iPhone in recovery mode and perform a restore. If you're still unable to complete the setup assistant due to an activation error, contact Apple for assistance.
Hope that helps,
David

Few questions about "city explorer"

- I noticed it can tell me where the metro is, but could nokia maps + city explorer tell me what line should i take in the metro and which station i should go out?
- Does it all require data transfering while i'm walking, or can i donwload it all before, where i have wifi? (like nokia map-loader)
- same question about the guides...
Thank's!

You can find most of the answers here - or to links to the answers -
http://help.sap.com/businessobject/product_guides/boexplXI32/en/exp_acc_admin_en.pdf
I haven't used the Explorer accelerated for a long time, but as far as I remember in rsddstat i think you can identify the explorer usage from the user id, but not sure - try and see.
You can also run all your BIA indexes at the same time if you want to, the algorithm takes care of the table locks and switch to other index
Querysnap shot index is a SNAPSHOT of the data at the time of the index - it will never change unless you re-run the query and index it. Regular BWA indexes gets updated when you load data to underlying cubes and run BWA rollups/change runs. The querysnap shot data will not change. I like them if my query output miliions of lines - such as ZCUSTOMER. With query snapshot, you can put all of them to explorer for customer segmentation etc purposes
