Hello - I need to replace my WiFi dongle on my trusty PAW Classic - could someone tell me what item/spec I should be ordering and from where please. Better still, a link to the purchase site for such an item would be awesome! I am non-technical so grateful for simple advice please. Thank you very much.

Hi SkyRanger1963,
Please PM me your Email Address, and I’ll post a new Wi-fi dongle to you FOC.
Kind regards,
Ashley

Just a quick question:- I'm guessing that the dongles have a built in battery to enable memory of recent location. Does this fail over time ? as mine seems to take significantly longer to get a location fix now.

Wifi Dongles don't have any battery backup
I assume you're referring to the GPS ..?
They take a note of their location when starting - if the GPS isn't where it's expecting to be after its last start up then it can take longer to get a fix and download the ephemeris /almanac data …
Have a read here … it interesting!! https://en.wikipedia.org/wiki/Global_Positioning_System

Thanks for the link Sean.
I'm just trying to figure out why it's taking so long to get a position fix for Skydemon. It always used to be really quick, now taking several minutes, even after being switched off for a short while in the same location.
I have another GPS dongle somewhere, I must find it and see if there's any difference.

Hi Brian
Haven’t heard of this, but guess it’s possible...
Thx

The GPS dongles do have a small button cell, to enable it to warm start. These are not rechargeable so will die after a while. So when it goes they will cold start every time, so an initial fix will be in the order of a minute or two.
I did comment on this on here many moons ago, it was a discussion about the GPS dongles from memory.

Thanks very much Ashley - PM just sent.

Thanks very much. Is there any advantage in getting one which has an aerial
-
BTW, perhaps should have said for completeness that PAW was upgraded a while back to Pi3 .... does this affect anything wifi related?
-
If you upgraded to a Pi3 then you don’t need a WiFi dongle or antenna.

If you upgraded to a Pi3 then you don’t need a WiFi dongle or antenna.
To clarify, you still need the 2 antennas for PilotAware & ADS-B
but no WiFi dongle is required.
In which case returning to the original query

why do you think you need to replace your Wifi Dongle ?
If you are experiencing some kind of problem, its probably best to describe the problem, then we can suggest a solution ?
thx

Thanks ... the problem is that from time to time (several times on some flights) I lose gps signal on a tablet running skydemon linked to PAW. I was told the wifi dongle was the most likely culprit. I bought a new one which, not realising the variation of chipsets, didn't work. I'm now a bit confused about the comment that no wifi dongle is needed with Pi3 as I thought my unit had been upgraded. I'm checking with my local guru to find out exactly what spec I'm at. In the meantime any advice welcome. Thanks :)
ps ..... just discovered that my upgrade was to Pi2 Mode B ...............not Pi3.

Hi AMO,
(RPi3, has integrated WiFi and does not require USB dongle)
OK, I understand, let me ask the following
1. What power supply do you use
2. Do you use the provided power cable
3. What PilotAware software version are you running 20180520 or 20190621 (shown on Home page)
4. What type of tablet device are you using (I see you use SkyDemon)
5. What 3rd Party connection type from SkyDemon doyou use ?
Thx
Lee

The unit was built by a friend in the very early days and I upgraded it to pi2. If I've understood them correctly .... answers to your Q are as follows:
1. What power supply do you use - an unbranded 12v to USB outlet (1.1 amp I think)
2. Do you use the provided power cable - an unbranded USB cable - nothing was provided - see above
3. What PilotAware software version are you running 20180520 or 20190621 (shown on Home page) - recently changed to 20190621- but same problem occurred with earlier vers
4. What type of tablet device are you using (I see you use SkyDemon) Samsung S2 but same problem occurs with Nexus 7 and motorola mob
5. What 3rd Party connection type from SkyDemon do you use ? PAW
Obviously not as straightforward as I thought !
-
It might be as straightforward. I've had problems with two of these Wifi dongles now. Latest one's just gone in the bin. ;D I had a couple more in my drawer and a replacement has made things hunky dorey again.

On the ebay link you sent previously, is there any particular one (supplier) that you know is good and what's your advice on aerial versus no aerial. Thanks
-
I'd go for one without the aerial, it'll only get in the way! ;D
I can't speak for one or the other. They are advertised as RT5370 chipset devices. A friend bought one which looked like the one with the aerial but it had the wrong chipset. There are others which look like the one without the aerial but they have other chipsets such as the 8188 and such, which won't work. Here's one with the 8188 - don't get this one:
https://www.ebay.co.uk/itm/Mini-Realtek-RTL8188-USB-WiFi-802-11B-G-N-Wireless-Adapter-Network-Dongle-Hot/254224278100 (https://www.ebay.co.uk/itm/Mini-Realtek-RTL8188-USB-WiFi-802-11B-G-N-Wireless-Adapter-Network-Dongle-Hot/254224278100)
There are some which look correct, but don't say which chipset they have, like the following:
https://www.ebay.co.uk/itm/USB-Wireless-Laptop-Mini-Dongle-802-11n-g-b-WIFI-Network-Adapter-WLAN-150Mbps-Y/401767527051 (https://www.ebay.co.uk/itm/USB-Wireless-Laptop-Mini-Dongle-802-11n-g-b-WIFI-Network-Adapter-WLAN-150Mbps-Y/401767527051)
It may have the correct chipset, it may not. Who knows? :o
At least if you get one advertising RT5370 then you can get your money back if it turns out it's not the case. Can't recommend any particular suppliers, they seem to come and go and the prices come and go as well.
I ordered a couple of SDR dongles which were advertised as having R820T tuners, which turned out to have E4000 tuners. Ok generally, but no good for 1090MHz ADS-B. They gave my my money back after they asked me if I could use them at all. I replied, "Not for the application I wanted them for, no."

AMO. In response to your answers
A screenshot of your PAW home page will tell us if there is a power issue.
1. A power supply capable of 1.1A is insufficient. Minimum is 2.1A See this topic http://forum.pilotaware.com/index.php/topic,1285.0.html
2. It is also unlikely that an unbranded USB cable will meet the minimum specification. It must be no longer than 1m and use a conductor no smaller than 20AWG . https://www.juicebitz.co.uk/heavy-duty-braided-fast-micro-usb-charger-cable-for-samsung-galaxy-s5-s6-s7-edge-black-1m-metre.

Thanks to all for your various steers. I do recall checking the status line on the home page and everything was good - ie not power throttling. It's also a bit odd that for a year or two the installation, including power supply/leads, has worked flawlessly - so what's changed? I'll investigate and report back. Thanks.
-
Change the power supply for an Anker 1000 and the lead for a juicebitz one with 20 AWG thickness

New Anker USB (cigarette lighter) power adapter fitted and no wifi drop outs on last 2 flights!! Thanks to all for good advice.
