Wifi for 2 houses separated by 270 meters

Hello all,
[sorry for my englsih]
We need to have a Wifi access between 2 houses separated by 270 meters.
We think to buy an Aironet 1240AG (AIR-LAP1242AG-E-K9) access point but we don't know which antenna to choose.
I can install the antenna on the roof of my house and access point inside house.
In France we are limited at 100mW (20dbm)
Question 1:
Is it possible that Wifi do that ?
Question 2:
Does the signal will be correct (minimum 11~15 Mbps) in the second house using an usb wifi key receptor or a wifi network card with antenna receptor ? This connection will be used only for Internet access.
Question 3:
Which antenna choose for my roof ?
Question 4:
If I buy an antenna today, will I do to change it for the next generation of Wifi 802.11n ?
You can see a photo of the 2 houses.
Thanks your for your help ;)

Do you have line of sight between the 2 houses?
are there any obstacles in the way? Hard to tell from the picture.
Also, are there any other wifi signals in use?
You have 802.11a available based on your APs, it may be a better choice if there is a lot of 2.4 GHz signal in the area as well.
here is a link for the cisco antennas
http://www.cisco.com/en/US/products/hw/wireless/ps469/products_data_sheet09186a008022b11b.html
Something like the AIR-ANT58G10SSA-N is rated for 8 miles, but you will need N to rp-tng adapters for your APs. Also, if you plan on mounting the antennas outside, you should invest in some lightening suppression for the antenna.
given the power restriction, the cable length, the suppressor, the converter and finally the antenna, you can calculate the signal.
Yes, it is possible to do it, but there are many factors that will affect performance.
Yes, you will definitely have to buy a new antenna AND radio for 802.11n. There may be a radio module available for the 1240 down the road for all we know.

For me, a time capsule is even safe when you have whatter damage op fire in your house. Am I wrong or is it just an additional HD like there are so maney with the only advantage that it goes automatically via your wifi for apple devices?

Jloe,
As I have posted before, You, and others having issues with Verizon would be much better off if you complained to the FCC and FTC as well as your Senators and Congressmen. We, as individuals, have such small voices - use them where they might do the most good.
Also, don't assume that Verizon doesn't monitor these postings, they actively do & sometimes contact those that post complaints.
Sorry for your problems. GC

POP3 & IMAP Email setup for both Wifi & Cell use separately...

Hello,
I was asked to post info about this by an iPhone support rep.
I initially had lots of trouble setting accounts for use with both my WiFi home and office networks and for use through the ATT cell network.
If you have a question as to how to setup email for both WiFi and Cell use, answer is you can't configure these manually and you don't want to...the phone does this automatically...and seamlessly. (you will NOT see the change in the advanced settings menu, this occurs internally, the settings appear the same)
The problem: Accounts changing settings automatically...when manually configuring two separate accounts with the same email address but trying to setup the outgoing settings for different ports...one for WiFi (your broadband server acct / port 587) and one for Cell (cwmx.com / port 25)...THIS WON'T WORK!! My WiFi configured email accounts would automatically switch to Cellular configured email accounts as long as they had the same email address. Even though I gave them different names, the phone looks at the "actual email address" and if they are the same it changes your configuration to match the other account (it does this by matching the account that was either ON or OFF first and as soon as you match the second account to that setting (either ON or OFF) the phone switches the settings to match the first account.
The Solution: (End of the Story first for those who have or are facing this problem): Be sure to setup the email accounts for use with your WiFi account first (and ONLY), as when you leave the WiFi area or turn off the WiFi setting the email account will automatically reconfigure itself for use with the ATT Cellular network...then the settings will switch back when you re-connect to the WiFi area(s). The settings that you will "SEE" are your setup for WiFi, this will not change even when using the Edge network (at least not what is displayed in the "advanced" menu). You will still see Port 587, even though the phone is changing setups internally and changes back once back on a WiFi network, you just don't see the changes.
*I hope this helps!*
(more details below for those who might be interested and _for those who may be trying to setup using COMCAST Broadband_)...
My issue began because I could not get my Comcast setup to work for outgoing email. So I was advised to setup for the Edge port settings by an iPhone support person from ATT...this was a huge error. Because I attempted to do this it actually kept the phone from smoothly converting settings as needed. I only discovered this after resolving the actual problem with my WiFi (Comcast Broadband settings) issue which was actually the setup that MUST HAVE a user ID and Password, at least when using a Comcast Broadband account. Unlike the rest of my XP and ME computers on my networks which do not require this info, the iPhone DOES.
Because I could not get outgoing mail to work with my broadband setup I attempted to setup two accounts for each email address...one for Cellular and one for WiFi for when I would figure out my problem...or for just sending email more quickly. This does not work as the conflict causes a nightmare. This is something the iPhone support folks should have explained but failed to do so, perhaps as they didn't know this?
Bottom line: Let the phone do the choosing...it works great and will avoid YOU wasting TWO DAYS and more than 12 hours on the phone with iPhone Support as I did. I eventually figured the port switching issues and solutions on my own through trial and error and luckily one bright iPhone support person advised me that he knew for sure that when using the iPhone with Comcast you must setup "outgoing settings" using an "ID" and "Password" which I was provided by Comcast in only a few minutes. I don't use their emial account but I setup one just for this purpose. Once done, my email accounts began working normally. Once I resolved the conflict issues listed above the phone now works great both WiFi and Cell.

fullspool,
Comcast offers an authenticating SMTP server that should work for you on WiFi and EDGE both.
The settings are linked in this Apple knowledge base article:
http://docs.info.apple.com/article.html?artnum=306074
The Comcast link is:
http://www.comcast.net/help/faq/index.jsp?faq=Emailtop18913
From that link the settings are:
Your email address: [email protected]
The email server type (POP)
Incoming mail server: mail.comcast.net
Outgoing mail server: smtp.comcast.net
With SSL on for both incoming and outgoing.
Hope this helps,

Can i return my ipad wifi for a wifi 3G eventhough it's engraved?

Can i return my ipad wifi for a wifi 3G even though it's engraved?

According to Apple's customer service line you can return an engraved iPad for an exchange, but it's not clear if it's within 14 or 30 days. If you call they says 30, but their site says 14. I think it has to be purchased straight through Apple though. Contact where you bought it from and tell them you are thinking of buying a iPad and having it engraved, but are concerned about the refund policy. They'll explain it in more detail at that time.

I'm buying a 4s tomorrow, can i use my old 3gs as an itouch with wifi for my kid?

I'm buying a 4s tomorrow, but i was wondering if i can use my old 3gs as an itouch with wifi for my son to use?

Yes of course, that is possible.
The iPhone works just like an iPod Touch if you don't insert a SIM card. It will just display "No SIM" instead of the signal bars.
The "Phone and Message Apps" will still be visible, but basically the phone won't call or text anyway, because it lacks the SIM card.
Best Regards

No Option for Printing Separations in Acrobat 11

I do not have the option to print separations from Acrobat Pro 11 on OSX Yosemite. I have installed the PPDs and they work in Illustrator and InDesign but do not work in Acrobat.
First, I am a designer at a screen printing shop and have been printing separations on a daily basis for 3 years. I understand how it works. I was working on a PC with CS 5.5. Typical workflow was to design in Illustrator, Print to PDF, open the PDF in Acrobat, save as EPS. EPS was the preferred method since I print the transparencies from Illustrator, and since Illustrator can only open one page of a PDF at a time, I saved the PDF as EPS so that ever spot color got it’s own EPS file. From there, I created a new AI file, put all EPS files on different art boards and printed.
Now I am on a Mac with Yosemite and CC 2014. I know the PDF workflow changed in Snow Leopard. You now have to print to a PostScript file and Distill, which then gives me the PDF i can open w Acrobat and save to EPS as usual.
But, I decided to really dig into Acrobat 11 since it has all the Ink Manager and Preflight features. My preferred workflow would be creation in AI, save a PDF, then use all of Acrobats features for the final check and separations. The Acrobat manual says on page 316:
“Print separations
1. Choose File > Print, and choose a printer.
2. Choose an option from the Comments and Forms menu.
3. Choose print range and page handling options.
4. Click Advanced.
5. If you created a custom printer settings file with the appropriate separation settings, choose it from the Settings menu at the top of the
Advanced Print Setup dialog box.
6. Select Output on the left, and choose an option from the Color menu:
Choose Separations if the PPD doesn’t support in-RIP separations.
12. Click PostScript Options on the left, and select settings as needed. Click OK to close the dialog box, and then click OK again to print the separations.”
The only option I have in the print dialog is my desktop printer.
I have installed the PPDs, which brings me to another problem.

which is the adobe.sit.hqx file that contains 5 files with no file extension. Per the “Read Me” instructions, I have placed the “Acrobat Distiller (no file extension)” file in the
Library/Printers: PPDs: Contents: Resources: folder.
It works with Illustrator, and is not really and issue.
-The file is a 17KB file with no extension that was last modified on 9/9/2001.
Following another page

it give the link
Acrobat 9 PPD
which is the ADPDF9.PPD file, a 29 KB PPD file last modified on 12/8/2014.
Just to test it out, I placed both files in the
Library/Printers: PPDs: Contents: Resources: folder. Both are selectable from Illustrator when printing a PostScript file and both seem to work. I see no real difference between them.
I also created the PPDs file in the Presets folder of InDesign and can get separations from there as well.
But, I do not have the PostScript or any other print option from the Acrobat print dialog except for my desktop printer.
SO,
1) Is there somewhere else I need to place the PPDs for Acrobat to see it? The manual states I should be able to print the separations from the Print Dialog but its not available.
2) What is the difference between the “Acrobat Distiller” file and the “ADPDF9.PPD” files? Different size, different dates, but no obvious difference in output.
3) I sometimes print halftone jobs through AccuRip. I have gotten pretty good at manual spot color transparency gradients within illustrator, where I create complex gradients using only a spot color and a gradient with 100% transparency on one end and 0% on the other. But if I have many colors in it, I have to print separations through PotsScript and then Distill it, which flattens all transparency on the separated file. The result is a separation with a placed image gradient with a clipping mask instead of a true vector gradient. I know it has to be flattened when it’s ripped anyway, but I would like for it to ONLY get flattened as it passed through the rip on its way to the transparency, and not during the Distiller separation which then is placed back in AI for printing. Is there any way to do this on a Mac which MUST be printed to PostScript and Distilled?
Thanks

“I’ll never give you a job to print.”
Lead with an insult, good start.
You know, I read your comment, and the link, right before I went to bed. I thought I would respond then, but thought I should sleep on it. Well I slept on it, and I’m actually MORE p***ed off today than last night. I will try to keep this as professional as possible…
“Such an outdated time consuming workflow !!!”
No S**t (so much for professional). Which is why it’s unfortunate that Apple forced this workflow on people like me.
I asked SPECIFICALLY about color SEPARATIONS in the title of the post and throughout the post. The link you provided did not provide an answer to this. It explained how terrible “refrying” a PDF can be. And what was the solution it gave?
“Use EPS and not PostScript!”
Strange. it seems that is the EXACT workflow I listed! To quote myself;
“Typical workflow was to design in Illustrator, Print to PDF, open the PDF in Acrobat, save as EPS”
That was on a PC, where Print to PDF is still an option. The design is made in Illustrator with Spot Colors, all overprints are set, because a human will be lining up the screens to print by hand, and you need about .5 - 1 point of “play” for when the screen moves so abutting colors will not have a gap of shirt color between them. I can then use all of the functionality of the AI print dialog box and print the SEPARATIONS to a PDF file, and the PDF is then split to separate EPS files for easier control.
Apple in it’s infinite wisdom has taken away this functionality. From AI, my 2 listed printers are my desktop printer and an Adobe PostScript file. Remember, I am SEPARATING the artwork to be printed on vellums that will be used to burn a screen. If I leave my desktop printer active, I can select “Setup”, where i am brought to the system print dialog box, where if I select “Adobe PDF” or “Save as PDF”, I get the message from Illustrator that “The Save as PDF option in the Printer dialog box are not supported”.
So, if I change the Printer to “Adobe Postscript file”, the “Setup” box is greyed out. If I simple “Save As” and choose PDF, I do not have the option to SEPARATE colors. Do you see the dilemma now? Apple remove the functionality I have on a PC, so my SEPARATIONS can not be saved directly to a PDF, but MUST me “printed” to a Post Script file, which then MUST be distilled to get a PDF of SEPARATIONS.
Which brings me back to the whole point of my post.
““Such an outdated time consuming workflow !!!”
Right, which is why I’m trying to avoid it. In reality, the entire process only involves 1 extra step over the PC workflow, and the Distill process literally takes a few seconds. But, I don’t want to Distill for all the reasons listed in the link you provided. And if i follow the advice of the link, saving to EPS, I DO NOT have the option of SEPARATIONS. Which is why I’m trying to save a PDF from AI, the use all the functionality of Acrobat Pro to SEPARATE my colors. Again, the manual to Acrobat says I can print my SEPARATIONS to a file, but I only have the option to print to my desktop printer from the Acrobat Print Dialog box, even though I have DO have other options in AI and InDesign.
So, great Adobe MVP, can you answer my original questions?
1- why do I not have the option to print to a file in Acrobat Pro?
2- What is the difference between the “Acrobat Distiller” file and the “ADPDF9.PPD” files? Different size, different dates, but no obvious difference in output. (Not what I want to use, but on OSX post 10.6, I don’t really have a choice it seems)
3- Is there any way to print to a SEPARATION file on a Mac without printing to PostScript and then being Distilled?
I see your skills are:
“PDF forms, PDF multimedia, eBooks in PDF or in ePub format.
I'm an InDesign Digital Publishing Suite specialist too. I am also a trainer and the webmaster of abracadabraPDF.net, the only French web site dedicated to PDF and Acrobat.”
Good for you. Have you EVER had to print separations for a t-shirt? Have you ever had to consider that a person will be physically pushing the ink through a screen, so you must consider the thickness of the ink, how that will interact with the mesh of the screen, which determines the LPI the halftones are printed at, which determines how fine your gradients should be? Because I do it everyday. So your whole “I’ll never give you a job” thing is especially infuriating, and pretty unprofessional.
So not only have you totally ignored all my questions, you insulted me and given me a link that ALSO answers none of my questions. I am also assuming, though I could be wrong, that you marked your answer as correct int he AcrobatUsers forums. Well guess what? Even with you MVP badge, you are NOT correct. At least not for what I’m asking.
If I ever need an eBook, PDF form, ePub or Multimedia PDF done, maybe I’ll use you. But, I would never hire you for color separations for t-shirt printing.

Ipod touch 3rd generation will connect to my wifi for a few seconds and then nothing will load. help please?

I have an ipod touch 3rd generation 64gb and it has iOS 5.1.1 and it will connect to my WiFi for a few seconds and then nothing will load. It says I have full connection bbut nothing works. I have 2nd generation ipod and it connects fine. Along with my laptop and xbox 360. I have tried downgrading it and restoring it from itunes. I also tried forgetting the network and inputting it myself but it sti does the same thing. I even tried resetting my wireless modem but it still didnt make a change. I really could use some help. I can't call apple cause im no longer under warranty.

Reset the iPod and connect to its syncing computer. It it shows in iTunes restore the iPod.
Next see if placing the iPod in recovery mod will allow iTunes t see the iPod so you can restore the iPod. For recovery mode see:

Sharing ethernet from Macbook pro to wifi for my iphone.

Internet sharing has worked completely fine for me for about 3 weeks up until now. Now, when I try to connect to the network on my iPhone, it connects for about a second, then drops connection. (This connecting and disconnecting happens rapidly if I stay on the Wi-Fi choice tab on my phone.) The network shows 3 full bars for connectivity, however when I choose it and the flickering between "choose a network" and the actual network being chosen happens, the 3 bars become greyed out. It jumps from the list of network up to appearing as the chosen network about 5 times than stops (ending up back on the list to choose from). I'm not sure why this started. I tried to connect my friend's tablet to the network and the same thing happened so I know it is a problem with my computer and not my phone. I've restored and reset network settings on both my phone and macbook several times. I just installed mavericks today in hopes that it might fix something but the same problem occurs. My macbook is still able to connect to the internet just fine when sharing is turned on which leads me to believe that the ethernet cord I am using and the port on my macbook are perfectly fine. I haven't seen any problems similar to the one I am having right now so I am trying to explain it the best I can. Can anyone help me figure out what is going on and what (if anything) can be fixed? Also, for the sake of providing all helpful information, I am on a college campus in a dorm room so messing with the router or modem or anything like that is not an option. The reason I share the ethernet from my macbook to wifi for my phone is because the wifi from the college is horrible and I am forced to use up all of my data quickly while I am in my room unless I can get this sharing to start working again. If anyone has an possible solutions or theories as to what is happening please let me know! Thank you!
