just in case anyone will face the same issue. unfortunately I failed to find any newer firmware than the one I have but I found a guy in another forum who works a lot with Dahua cameras and he confirmed that it is a known problem for some of the Dahua models with wifi. the problem seems to be appearing on all cameras within one batch so the only way to fix this is to try a camera from another batch or just use the LAN connection. I did not have an option to exchange my camera so I used the LAN connection and the camera works perfectly since then.

unfortunately the power adaptor replacement did not help, the camera still looses the connectivity (however, seems to occur less often on the new adapter than on the old one). I also tried to place the camera very close to the router (3-4 m line of sight) but it did not help either. I am still looking for a newer firmware however I doubt it exists. I probably will be able to connect it via the LAN cable which will probably fix the issue but in that case what was the point to buy a WiFi camera... unfortunately I have no option to return or replace it.

I've seen that website already but I have absolutely no clue which firmware is suitable for my cameras and it is totally unclear from the filenames. I tried opening the description of the files one by one and search for anything related to HFW1200S-W but failed to find one. That's why I posted here in a hope that someone who has such cams already have a new firmware for them.

51cent, thanks for your reply! Unfortunately I already tried all that, i.e. factory reset and also changed the router, but no luck. Weird thing is that I also have a couple of DH-IPC-K35P which work perfectly fine with the same wireless setup. The last thing I decided to try was to switch the power adapters between K35P and HFW1200S-W. They both are 12V 1A but the ones I use on K35P are from factory and the ones I use for HFW1200S-W were bought separately and I hoped they are not giving stable enough power. It is too early to make any conclusions but they work fine for more than 24 hours now. Strange enough that K35P also works fine on the potentially "faulty" adapter. Anyway, if anyone have a newer firmware that I mentioned below please let me know. I also have an annoying software bug which I hope was fixed.

Hi All, I recently bought a pair of Dahua cams, model DH-IPC-HWF1200SP-W and they both lose connectivity quite often. I was in hope that firmware upgrade can help me but I can't find any fresh firmware for this model. I currently have: Device Type: IPC-HFW1200S-W Software Version: 2.212.0000.4.R, build : 2015-12-02 WEB Version: 3.2.1.311293 If someone could point me to anything newer than this I would be grateful. Thanks!
