Thanks to all TRADERS in here,
First of all I would like to thank you all for the input. I will certainly look into all your advice/tips. Unfortunately, I am not a computer wizz. I am better at Trading/scalping

, but for that everything has to run accordingly.
Some more info:
The thing is, I have this same problem when I was in Asia for 1/2year, with a NEW build pc, AMD Ryzen 7 3700X, Corsair DDR4 Vengeance LPX 2x16GB 3200, Samsung 970 EVO 1TB M.2 SSD.....(Nov 2019), so I don't think it could be the PC. The pc I am using now, is almost similar to the one mentioned above, just as fast but a year older.
My connection, is hard wired, NO Wifi, I have a margin account, with live datafeed for all US instruments, so NO paper account. The internet is Download ~255 Mb/s, Upload ~26 Mb/s, Ping ~18ms.
No other software running beside TWSlatest/Beta/Stable. NO VIRUS software (since I don't do anything else on this pc), Firewall ON but I don't think is the issue, cause the issue mostly/only occurs, during US RTH and that is around 15:30-22:30 CET (09:30-16:30 US Easter Time).
My region setting is Europe, but my time setting is US ET (NewYork time), for right time in my charts.
One thing I found out is that my pc, somehow cannot open the Interactivebrokers.com website. After clearing all history in Chrome, I will be able to open the website only once, but the second time, I see "Site is unavailable". Interactivebrokers.co.uk is not a problem. ANYONE have any idea about this issue?
When problem still persists, after completely new installation of Windows, on my harddisk I still have a few options.
-I am considering Glassfiber connection, but it takes about 2 weeks to have that all set up, without any guarantees.
-Second/NEW PC
-Another broker, which will be my last resort

(, since I think IB is the best by lack for any better. (I trade futures, Options, but because of this issue, I am forced to trade stocks only, because with stocks, not every second delay is deadly)
Reading all your tips, I have to conclude that i am the only one with bad luck

, I can not, and WILL NOT accept this issue, how frustating it might be to solve.
Once again, MANY THANKS for the input so far, and I do appreciate any further suggestions or tips.
Phuong_rdam@yahoo.com for any tips or suggestions / or pm is also ok. THANKS
Greetings from SAD SAD Phuong from Europe
