Both Android and Windows are included in the download. You can chose which one(s) you want to apply.

Thanks. What I meant though, is there any reason to upgradr the windows portion? I’ve done the upgrade to 1.05 now for the android.

Oh, I see Teclast uploaded a C2D4 package onto their firmware download section on 30/09/2016. Does anyone know if this is the stock setup or an update? I did email them to ask… but they’ll never reply.

I can’t download it now anyway, they’ve reached their download limit or something.

Ok, so I’ve put the stock setup back in, but trimmed up a bunch of things inside the case so that it sits closer to the camera. In doing this I can get the +’ve portion of the antenna to stick out almost entirely and wrap it round and stick it to the screen (as some people have suggested already). The results are dramatic. I had tried this trick already, but I couldn’t get as much of the antenna out before. Now with basically the entire live portion outside of the case, I can actually use the thing all around the house. The throughput still isn’t great, but the latency and usability are almost perfect.

I’m somewhat happy for now. This is all in Android, so I’m hoping that in Windows it’ll be even better.

Hey guys,

I opened my c2d4 up and replaced the wifi antenna with one from an iPad 2 (got the antenna cheap from a repair place). The wifi might be ever so slightly better, but is still pretty poor.

What I did notice though, is that the signal strength is reported about the same as on my android phone and other tablets (using a WiFi analyser app), the only difference is is that they work perfectly even on low signal, like in the negative 70’s and below. The teclast will only work well with anything in the low sixties or high fifties. So I’m thinking it’s not really a signal strength issue, but more a noise issue.

That’s where my expertise ends though. I noticed that the WiFi chip is soldered to a small daughter board, which is then soldered to the main board. Does this mean that one may be able to replace the WiFi chipset with something better?

After reading this thread and watching this video: YouTube I bit the bullet and opened my X98 plus II with the equivalent of a guitar pick. A couple of observations: – start with opening the case between the screen and the white of the back, away from the connectors, then work your way around; it opens very easily (take the SD card out first) – nothing connects to the metal back, so you can’t break any ribbon connectors or such – there is a surprising amount of space left inside, enough for an alternative wi-fi antenna, especially between the two speakers – 3 out of 4 screws of the speakers were loose, a bit of super glue and no more crackling sound I’ve got two retrofit wi-fi antennas on order from AliExpress and will report back if these make a difference.

Hey Golden,

Let us know what you find when you swap the antenna. Also post a pic if you can of your swap. I’d really like to know the results for a possible fix to my C2D4.

Thanks!
