I have been plagued by wi fi dropouts from my Samsung Galaxy for about 12 months and recently discovered the cause which I will share in a moment. I used Mobile AP on the Samsung and my signal strength is 4-5 bars.
The fix for the dropouts is so simple that I am almost embarrassed to share it.
Here is the fix: Do not share your wi fi with multiple devices. The more devices using the wi fi the greater the risk of dropouts.
If I want to use wi fi on my laptop I make sure that this is the only device connected and I place the phone beside the computer. If I want to use wi fi on the iPad via Mobile AP I make sure that is the only device connected and I place the phone in close proximity to the iPad.
Rule of Thumb – one device connected at a time, and only one device.
Hope this works for you if you have been plagued by dropouts. Look forward to your comments and feedback.
I found that I could increase the overall speed from 2.5Mbps to 3.7Mbps by placing the phone in an upright position. I did this by placing it in a metal toaster rack (the rack not the toaster) as shown in the photo below.
I recently exchanged my iPhone for a Samsung Galaxy smart phone.
I was delighted to find that the iPhone still works with data transmission on Wi-Fi without a SIM card. All the apps still work and I can send and receive emails. The iPhone is certainly not a throw away device and still extremely useful as a mini-computer.
The only feature that has been lost with the removal of the SIM card is the ability to send and receive telephone calls and text messages and connect using 3G. Needless to say it requires a Wi-Fi to function.
I you are not sure how to connect your iPhone to Wi-Fi then watch the video below.
