I’m using low budget Dlink DIR-841 dual band router in my home. I want to upgrade my router as well as want to use Wi-Fi 6.
I have a spare raspberry pi 3B. Using that I want to make a wireless router; if possible want to have Wi-Fi 6 in it. For getting good Wi-Fi service, definitely I need to purchase usb Wi-Fi module that’s ok for me.
Could anybody please suggest me whether it is a good idea? Also share a good reference of doing so.

My laptop has windows 10 but suddenly I encountered Wifi range issue that means my wifi is detecting wifi about one meter but not above that.I also reinstalled windows 10 but still problem exist.
what should I do?
Well the first thing to try would be to open up your laptop. From there you can take a look at the wifi card. It is possible that there is something obstructing it or its not fully in or anything.
The second option which is likely the one you will have to take is to purchase a cheap usb wifi adapter. They can be had for around $10 on Amazon usually. You can get them pretty much anywhere you can buy computers and tech products though.
I need to test my application on IPv6 network on iPhone. As far as I have learned, I have several options:
Share IPv6 Internet via iMac as described in this tutorial; though when I tried to follow the steps there on an MacBook Air connected by bluetooth to an iPhone with turned on 3G there was no "Create NAT64 Network" checkbox for step 7 - do I nessesarely need to be connected via cabel or I need a stationary iMac?
Configurate IPv6 wi-fi on a router; though as far as I have learned to do this I need some special router that supports IPv6 and my Internet provider should be able to give me IPv6 connection. Is this correct?
Are there other, maybe easier ways to simulate IPv6 on an iPhone? How do I tell router that supports IPv6 from the one that does not?
I know its a bit late, yet it might help someone. You can create an ipV6 network via step 1 described. The trick is, at the time of clicking on BluetoothPAN option, you should press the option(ALT) key in the keyboard. Then Create NAT64 Network checkbox will be displayed at the bottom. This is the same case for WIFI & Ethernet too
I am looking for a weekend project to do and I was wondering if this was possible. I have these radios that are programmed using Telnet (to set the frequencies, output power, etc.) and I normally do this with my computer in the terminal. The radios have an RS-232 connector on them and I use a USB converter to connect to my computer. Having a small, portable device to program them with instead of a big, clunky laptop would be great, so what I am hoping is possible is to be able to create a telnet connection with my iPhone. Is it possible to create a Telnet application for my iPhones that can connect to these radios through the USB/lightning port on the iPhone? I know normally when people write Telnet applications for the iPhone, they are using over the air connections like WiFi/3G/4G to connect to the internet, but this radio is not connected to the internet but its own private network of other radios. If it is possible to connect the iPhone to the RS-232 port and accomplish the Telnet connection (also without frying my iPhone with too much current) that would be fantastic. Also, if it is possible, how would I access the lightning port? Thanks!
EDIT: Another possible connection is the iPhones lightning port to an RJ-45 connection. That would work as well. Is this possible? Thanks!
As far as I know, you can always study the specification of the lightning connector, you can find it here : http://en.wikipedia.org/wiki/Lightning_(connector). You can try to play with the SDK, trying to send commands from the iPhone and receiving information through the cable. The problem of that, and I was working in several medical applications with the 30 pin connector and the lightning as well, is you have to spend a lot of time to deal with the specification. The most important part is to understand how the connector works and what can you send and receive through the cable. If not, you would have to build your own connector, which is interesting and can help to learn a lot, but it´s not an easy thing. In a project I was working, we had to build several cables to adapt the signals to connect with the device, in my case an iPad1 and recently an iPad 4 although it works with the iPhone as well. As you know, or you should, you will have to learn about MFI.
You can find some information regarding that point here : Create an iPad app that can send/receive data via the USB cable?, but bear in mind everything goes through MFI, so it has its pros and cons....most of them cons. You can find several information here : https://developer.apple.com/programs/mfi/
good luck :)
I want to get data from glucose meter devices by connecting into iPhone or iPad devices. I have different vendors glucose meters some uses simple HID interface for communicate and other uses serial communication.
These are the two possible ways of communication:
USB to 30-Pin connector.
3.5 jack to 30-Pin Connector.
USB or 3.5 jack will be connected to glucose meter and 30 pin connector will be attached with iDevice.
After having hours of research I did not find much help on internet for iOS specific.
I do find ORSSerialPort but I think it is for OS X apps only.
There is RedPark serial Cable but that is for RS232 to 30-Pin communication and secondly that can be only used in internal projects. I want to sell my application on Apple Store.
Someone also was discussing about using IOKit framework. We can communicate with iDevie but that is private framework.
Someone help me with this issue or let me know if that is even possible in iOS application.
Do Apple have any consideration on this type of working?
An iOS device can talk to external devices by following means of communications only:
Wifi
Bluetooth
GPRS &
GSM
USB (Don't exactly know what it is called)
There is no possible way to have RS232 serial port communication with iOS device.
Now What are the options left then?
Get a communication convertor in between your external device & iOS device. It can be
Serial to ethernet adapter
serial to USB adapter etc.
Embedd a wifi/bluetooth module in the external device (If it is being manufactured by you/your firm)
Have something with USB cable & mfi .(Never worked on this, but have seen stuff working with this). By something I meant, register your external device under MFI license & implement USB between devices (Again lack of clarity about USB stuff). Menwhile, I would appreciate edits on my answer by people who might improve it with USB stuff.
Update:
I visited the site of your vendor "glooko". I could not find any clue about them having any libraries for developers. So according to my opinion, they have kept their library private. They don't want you to develop apps based on their communication protocol. If you still need to develop apps for them, contact them here & let them know about your zeal.. M sure they will give you their private code. Anyhow, you don't need to register for any MFI or anything now. What you need is just the code they are using for communication & about that, nobody other than them can help you. So, all the best .. :)
Update 2:
What I understood from your updated question is, you want to create an iOS application that works with various Glucose meters, from different vendors. In a way you can call it as "universal Glucose meter app"
The short and straight answer for this is .."You Can't" . But wait, apple is not responsible for this. Neither it is impossible.
Let me tell you why. When you want your application to talk with a hardware device, there must be a communication channel between you too. You are well aware of those two options available. now, if your app must run on iDevices, the communication channel cables must be registered for mfi. Here that is also not the issue.
What is the issue then?
Different vendons don't generally follow the same communication protocols between their hardware & softwares. What happens if a german commander commands to indian soldier. Obviously, nobody will understand.
So, to achieve your objective, the only way is, you have to include SDK provided by each supported vendors in your app. Let me know if you are not yet clear..:)
There is a device called Lightning Serial Cable, the link is following.Take a look at their SDK.

It seems work with your application. I'm also looking for the solution that iOS device can talk to another device via serial port. In PC world, all PC has USB ports, so there is large amount of USB to serial port devices and vendors, such as FTDI and Prolific. I don't know if similar situation happens in iOS world.
Unless you join the Made For iPhone program you can not directly connect anything to an iOS device unless you use Bluetooth or TCP/IP.
I've been tasked with getting an iPad to talk to an external device wirelessly on the cheap. I tried the Bluetooth route (not LE - need higher data transfer rate), but we're not willing to go through MFi.
So now I'm looking at WiFi. It may be possible to configure my external device to act as a WiFi router, but it may be easier to get the iPad to act as the router. That's what I'm trying to figure out here.
So I've thought of two possibilities, neither of which I could find any answers for on Google or within SO. Does anyone know the answer to any of these?
Is it possible to have the iPad act as a WiFi router such that other devices connect to the iPad and can communicate with an app on the iPad?
When built-in tethering is active on the iPad, does the iPad have an IP address that is visible to any device connected to the iPad's WiFi hotspot?
When built-in tethering is active of the iPad, is there a way for the iPad to get notified of connections made to the hotspot and get the IP addresses of those devices?
A little more specifically, I need a way for a device to wirelessly communicate with an app on the iPad. I've already gone through the Bluetooth route and I'm hoping for a WiFi answer.
Thank you.
In the interest of not leaving a question open, I'll answer with what I've found:
No
As far as I've been able to tell in my research and experimentation, there is no way to do what I was hoping for. Thank you to Brad Larson for doing his best to give me options.
