February 12, 20179 yr Most of the time the remote CDU works fine, but regularly I notice that the response back and forth between pc and tablet gets slowed down, that I'm waiting for the signal to send for like 30seconds or more. Also, when the slowing gets to its worst, I get complete hang-ups, that the remote CDU doesnt repsond at all, for extended periods of time, this can be 5 minutes, but also 15-20minutes. The CDU in the sim is still usable, but the remote CDU is not following along. What might be wrong and what can I do about it? Cheers! Maarten
February 12, 20179 yr Commercial Member Hi Maarten, what device/browser are you using? The only time I have seen such behavior was with a very poor wifi connection where the tablet was losing its connection. How is your reception? Regards Mark Mark Foti Author of aviaworx - https://www.aviaworx.com
February 12, 20179 yr Author Using Samsung SM550-T and I used Chrome to setup a browser window as app. On my tablet it shows that the wifi-connection is as high as it can be, although it does go up and down a bit, at times, but nothing dramatic, or anything... I noticed that when I get those hang-ups, when I use the app, the CDU in the sim still follows along, only what happens in the sim doesnt follow along on the app. After a while the page on the app jumps to relevant one and it works for a while again, but at some point it will get stuck again. I'm using Win10 64-bit, with P3D v3.4.18, PMDG 747v3, just in case that info might be useful. Cheers! Maarten
February 12, 20179 yr Commercial Member Hi Maarten, what version of Android is that running? Do you have a different device you could test? Me personally I'm using an old Nexus 7 from 2012 which has become too slow for daily usage but does a good job as a CDU. Also running Chrome. So I can't say I've seen the issues you are reporting. Is your PC connected to the network using cable or also WiFi? Regards Mark Mark Foti Author of aviaworx - https://www.aviaworx.com
February 13, 20179 yr Author Android 5.1.1 I had to borrow one, but I got it tested now and it works the same on both tablets. I noticed that when I touch the screen, when the app is seemingly frozen, the screen reacts to my touch. Also the CDU in the VC repsonds to this signal, it's only the picture on the tablet that stays frozen. My pc is connected by cable Cheers! Maarten
February 13, 20179 yr A strong signal alone is not a definitive indication of a good wifi signal. If you have a neighbor or neighbors running high-bandwidth across the same wifi channel, it can make an otherwise strong wifi signal nearly unusable for real-time applications. I moved my iPads to 5GHz for this reason...neighbor's kid was streaming video from their 2.4GHz wifi router and it was clobbering my wifi in the house. Moving wifi channels and/or bands might be worth a try.

February 13, 20179 yr Commercial Member Maarten, can you open this site on your tablet's browser and see what sort of up/download rates you get? http://speedof.me/ See if you have fluctuating speeds or if its constant. Regards Mark Mark Foti Author of aviaworx - https://www.aviaworx.com

Moving wifi channels and/or bands might be worth a try. I tried this, let's see if this makes some improvement. can you open this site on your tablet's browser and see what sort of up/download rates you get? http://speedof.me/ See if you have fluctuating speeds or if its constant. I did a series of tests and I got some fluctuating results: Test 1: 2.28 Mbps Down / 0.62 Mbps Up Test 2: 1.53 Down / 0.27 Up Test 3: 3.60 Down / 0.62 Up Test 4: 2.20 Down / 0.78 Up Test 5: 2.89 Down / 0.50 Up Test 6: 1.68 Down / 0.59 Up Cheers!

February 14, 20179 yr Commercial Member Hi Maarten, those values show quite a bit of fluctuation. Can you please run the same test on your PC and compare? Regards Mark Mark Foti Author of aviaworx - https://www.aviaworx.com
February 14, 20179 yr Author Sure, here it goes: Test 1: 17.19 Mbps Down / 16.20 Mbps Up Test 2: 110.14 Down / 10.78 Up Test 3: 143.85 Down / 15.82 Up Test 4: 162.51 Down / 16.11 Up Test 5: 166.12 Down / 15.28 Up Cheers! Maarten
February 14, 20179 yr Commercial Member Ok that would indicate that you are losing a lot of bandwidth through WiFi (1-2% of your router's capacity!) Yes, the suggestion with 5GHz is a good one - the 2.4 GHz spectrum is often saturated in cities. What sort of download rates do you see on the tablet after making the switch? Mark Foti Author of aviaworx - https://www.aviaworx.com
February 15, 20179 yr Author Download rates have changed dramatically: Test1: 32.98 Down / 0.67 Up Test2: 35.01 Down / 15.45 Up Test3: 33.68 Down / 16.01 Up Test4: 28.15 Down / 14.13 Up Test5: 30.70 Down / 15.81 Up The speed of response from PC to tablet, as well as tablet to PC has increased loads. When I push a button on the FMC, I immediatelly see the FMC in the VC respond, but still, the picture on the FMC doesnt always change accordingly. Its clear that the PC has recognised the changes I made, but it can take up to several minutes for the picture on the FMC to change. To me it doesnt seem that there is any problem with slow data between the FMC and the VC, it s just the picture ont eh FMC that gets stuck. Cheers! Maarten
February 15, 20179 yr Commercial Member Hi Maarten, it's good to see your download rates have increased on your tablet. I'm not too sure what you mean by "The speed of response from PC to tablet, as well as tablet to PC has increased loads. "? Do you have any antivirus or firewall application running on your PC (other than default MS)? If so, try disabling them temporarily. What about other addons? Do you have a different PC/Notebook connected through network where you could try the CDU to see what's causing this? The typical delay should be within 1 sec from key press to seeing an updated screen - definitely not more than 10 secs or even a minute. This is the first time I am reading about this and I'm currently clueless as to the cause. Best Regards Mark Mark Foti Author of aviaworx - https://www.aviaworx.com
February 16, 20179 yr Author What I mean by that is that signals send between 2 machines can often have a little delay, but now I dont see any noticable delay at all, so the hang-ups are unlikely caused by a slow signal. I understand your predicament, things like this are, as far as I have seen, always related to delay in the signal, but I can keep using the buttons on the tablet FMC and the FMC in the VC responds at the same time, with no delay at all, while the picture on the tablet doesnt change. I can pick up my old laptop afrom a friend, this evening. I'll have a look if that makes any difference. Cheers! Maarten
