Worse WiFi Reception with iPad Pro

Has anyone else noticed that wifi reception is weaker with new iPad Pros? Mine performs worse in some parts of my home than my previous iPad Air. Or is my new iPad Pro (small) not working well?

Hello there jimpal!


Thanks for reaching out to the Apple Support Communities! It sounds like you are having an issue with the Wi-Fi signal on your iPad Pro. I know how important it is to be sure the Wi-Fi signal is strong when connected to the iPad pro. Check out this article with information about Potential sources of Wi-Fi and Bluetooth interference. It sounds like your iPad might be best served by following these steps and tips to see if it helps you with the connection.


Cheers!

Thanks to both sterling r and Tesserax for your useful and appropriate responses.


My wifi source is a new Time Capsule, which has been serving me well for nearly a year. The problem I am noticing with my iPad pro is at the remote ends of the home, where walls, etc., are bound to be a problem. However, earlier this year, coincidentally when I had my previous iPad Air, reception in those areas was better. So, before going looking into the wifi source, I thought I would ask this question about any known deficiencies with wifi in iPad Pro. And Tesserax has answered No.


I know it's odd, but I think weather may be a factor. In a separate wifi thread I noted that my area has had a summer of record-breaking heat and humidity when radio transmissions are bound to be worse. At least one of these worse-performing wifi areas in my home requires transfer through an outside wall, free of air conditioning. Even with A/C inside, humidity is higher. Worked well last winter and spring, but not during recent months. A couple of responders agreed heat and humidity could be a problem.


With no known iPad Pro wifi deficiencies, I will see if this improves as the weather gets back to fall/winter status. If not, I will just have to resort to Airport Express relays, or using the iPad closer to the Time Capsule.


Thanks for your advice.

As far as Wi-Fi interference is concerned, wireless network designers concentrate more on antenna design (both transmitter and receiver), distance between the two, building materials, and other competing RF sources in the same bands.


Weather typically does not get considered. However, weather does factor in somewhat with temperature having more of an influence than humidity. Humans, being mostly water, actually contribute more to interference, than humidity. 😉


What I believe you are experiencing is basic antenna design and its limitations. More so on the receiving side (iPad) than the transmitting side (Time Capsule).


Some advocate using higher transmitter power, but this does not solve the problem. What is really required is to improve the antenna's gain. For example, increasing the power of the Time Capsule Wi-Fi radio alone does nothing for the receive sensitivity of your iPad. Whereas increasing the antenna's gain improves both transmit (Tx) and receive (Rx) ends. Wireless clients rarely have problems hearing the wireless access point, but they have relatively weak Wi-Fi radios (aka, less power) and low gain antennas ... so they more often have more problems being heard by the same access point.


Some options are:

  1. Take signal quality measurements of the Time Capsule at the locations where you want to use the iPad.
  2. Use an application, like NetSpot to perform a RF site survey to determine areas with little or no coverage.
  3. Use the AirPort Utility on the iPad to take signal quality measurements, as follows:
    1. On the iPad, tap on Settings > AirPort Utility > Wi-Fi Scanner (enable)
    2. Exit Settings.
    3. Tap on the AirPort Utility > Wi-Fi Scan
    4. Leave Scan duration at Continuous.
    5. Tap on Scan.
    6. Let the scan run for 15-30 seconds, then tap on Stop.
    7. Note the RSSI values. This value represents how "strong" the Wi-Fi signal is at the location of the iPad. It is measuring the strength of your Time Capsule Wi-Fi radio signal at that same point. The lower negative the value is the stronger the perceived signal is.

Thanks for the tutorial on wifi scan. I hadn't used it before. Results put numbers on the situation I was experiencing.


Interestingly, I have an iMac in the same room where I have been experiencing the weak wifi on my iPad. The iMac shows a RSSI reading of about -72 dBm, while the iPad Pro scan (right at the iMac) shows about 10 lower (around -80 dBm). iStumbler shows S/N of around 30 for the iMac. Good but not great.


The iPad Pro shows a RSSI of about -40 dBm when I hold it right by the Time Capsule. Does this seem OK? My other experiences above lead me to believe that the iPad Pro may in fact be the weak performer here. It is using wifi channel 1. Is there a better one I should try?


Thanks for the help. I've learned a lot from your advice, no matter how this turns out.

That should be fine.

It is using wifi channel 1. Is there a better one I should try?

The channel any wireless client will use will depend on what the wireless access point is providing. By default, the AirPort base stations will broadcast on the "clearest" channel possible and choose this channel automatically. Unless you live in an area with a high concentration of other Wi-Fi network, there really shouldn't be any reason to try another channel. However, if you do, there are basically only three channels on the 2.4 GHz band that do not overlap. Those are 1, 6, or, 11.
