I am a user of Telit GE910-QUAD V3 modem (2G). The below table explains the Telit cellular modems and the TLS protocols they support.
Product SSLV3 TLSV1.0 TLSV1.1 TLSV1.2
(2G) N/A YES N/A N/A
(3G) YES YES YES N/A
(4G) YES YES YES YES
After seeing this, I doubt whether cellular technology (2G/3G/4G) plays any role in choosing the TLS version. Just for example, with 2G where data bandwidth and latency are poor, it might not be possible to use higher TLS versions.
Is there any reason why Telit 2G modems don't support higher TLS versions?
There is no reason that TLS 1.2 can not be run over 2G networks if TLS 1.0 can because these protocols are almost the same. My guess is that the 2G, 3G and 4G modems where simply created at different times and only the newer products support the newer TLS versions simply because these versions were not yet released or not seen as important at the time the software for the older modems was created.

I tried to use Windows Subsystem For Linux(WSL) 2 to use ubuntu 20.04 on Windows 10 and 11. But it has too bad internet speed in WSL2 ubuntu system. I had tried ubuntu on WSL1 as well, it also has too bad speed. It has almost 1/10 internet speed than host PC's internet speed in Task Manager / Performance.
I noticed that WSL Ethernet is working through Hyper-V Virtual Ethernet Adapter.
Is there any way to increase internet download speed in WSL2 by adjusting Hyper-V Virtual Ethernet Adapter Band-Width Limit or doing something else?

We have implemented TLS 1.2 on SERVER 2019, how can we know the best chiper suite used for IIS 10.
Please, someone, give me Priority Order would be great for me.
There is generally no "best" or "most secure" cipher suite you can use in all cases. Generally, when chosing a ciphersuite you want to support, you follow some principles to come up with a suitable cipher suite for your use case. Some of those are:
Chose ciphers which are supported by both your server and your intended clients
Eliminate insecure ciphers (e.g. cryptographically broken ones or ciphers with too small key sizes)
Performance considerations (ECDSA is faster than RSA but not supported everywhere, longer key sizes are (significantly) slower than smaller keysizes but are more secure, ...)
forward secrecy
...
If you don't want to deal with the propertyies of all the affected ciphers, there is a config generator maintained by Mozilla which can generate secure configurations for a variety of webservers for one of three security profiles at
https://ssl-config.mozilla.org/
You still need to decide based on the clients you intend to support and their supported ciphers which security profile is suitable.
An updated description of the available profiles along with some reasoning for the chosen options is available at https://wiki.mozilla.org/Security/Server_Side_TLS
To check your server and top get an overview about which browsers are able to connect to it, you could use the Qualys SSL Server Test at https://www.ssllabs.com/ssltest/

I am using win-sshfs to mount a remote drive from a Debian Linux server on a windows 7 64-bit desktop machine over the internet. The drive works but it is slow. I want to speed up win-sshfs by disabling compression and encryption. How can I do this? Otherwise is there a faster alternative?
i would suggest installing samba on your debian server or maybe a ftp server for large file transfers.
FTP is unencrypted and you can set different compression options,
windows can map a ftp:// share in explorer without any tools

I'm about to get an SSL Certificate for my website. In particular, it will be used because I'm switching over to a payment processor which requires it. A few "noob" questions:
1) Will I have to change any code that directs users to http://www.mysite.com to https://www.mysite.com, or will users who go to http://www.mysite.com be automatically re-directed to https://www.mysite.com?
2) I assume that https "slows" things down on a site? If this is the case, can I maintain the http everywhere on my site except when they make a payment to the processor? i.e. http://www.mysite.com/any_old_page.php, while https://www.mysite.com/pay_for_the_stuff.php
Thanks!
No, that won't happen automatically. You will have to change your server configuration to do that.
Yes, it slows things down. How much depends on the cipher suite used for the server, the server software and hardware. You should play around with different TLS cipher suites to see how much. It depends on that (and of the nature of your site) if you should only use TLS on part of your site or all of your site. As for the requirements of the payment processor: ASK!

I am using Wi-Fi connection for my android device. It is signal is very week and most of the time i am fed up with internet connection not available.
But i have a PC in my hand with which is in LAN connection.. Is there any way to use this internet connection my mobile using USB cable?
Just curious to know that this will solve my problem. If yes, please give me in detail.
PC LAN connection to Mobile is not at all possible. But, you can use the mobile connection in PC using USB tethering.
Yes it is possible. Look for "USB Reverse Tethering" in the google play store. It is not easy but it is possible.
There also another way to do this, with "Virtual WiFi Router", they use the of your computer as hotspot. But take care when you install it, always refuse all the program they try to install on your computer. It is possible to install without adware program.
Take a look at this. It is the ICS (Internet Connection Sharing) setup guide for Windows 7 on Microsoft's website: http://windows.microsoft.com/en-US/windows-vista/Using-...
