[ITJUNKIE]

Geplante Obsoleszenz?
Grössteil der Router verlieren nach 1 Jahr Ihre Leistung.
Nach Firmwareupdate wurde es noch schlimmer.
Warum?

Planned obsolescence?
Most routers lose their performance after 1 year.
After the firmware update it got worse.
Why?

What update did you do? firmware on it? 

What router is it connected to? 

If the performance decrease happened after a firmware update, did you try a factory reset and reinstall?

because it got even worse, I tried a firmware update, it did not make it any better.
Hardwareversion: EX7300
Firmwareversion: V1.0.2.158
it worked perfectly for over 1.5 years.
I use it as Access Point with a lan cable to my Vodafone Easy Box 904 Router.

What performance are you getting from it? 

Over 2.4ghz?

Over 5ghz?

[ITJUNKIE]

I tried both and every possibility.
My speedtest is every time ok but if i stream for example hd futbol, then i have every 15-30 Minutes connection interrupts.
