AI Thread Summary
Using an iPhone as a Wi-Fi host for another network is generally not supported, as it primarily functions as a basic Wi-Fi access point. The issue with the laptop's connection to public Wi-Fi may stem from its settings, which can be adjusted for better compatibility. Network profile software can help manage these settings automatically, but proper TCP/IP configuration is essential. While it may be theoretically possible for the iPhone to bridge to another network, it would likely require a specific app to achieve this functionality. Overall, the iPhone's capabilities as a Wi-Fi host are limited and may not meet the user's needs.

My laptop doesn't like public wifi for some reason but iphone has no problem connecting. Is there anyway to have my iphone become a hotspot with another wifi instead of 3g or 4g?

Sounds to me like your laptop settings are at fault. You need to change these when you use different hotspots.

You can get network profile software that will store and change these for you automatically but you need to get your TCP / IP settings correct first as it sounds like your laptop is set specifically to use your iphone at the moment.

As for the iphone, it's providing a basic wifi access point. I would be surprised if its capable of acting as a bridge to another network but its not impossible. You'd probably need to find an app for it though.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
