Are you certain both models are capable of 5.8?
Recently I bought a samsung Home Theater Model HT-TZ425 from my friend which quite new conditions and still in perfect condition in the box.
The problem is this HT is wireless rear speakers which works perfect but after while I realise the wireless give me lots interference with my Wi-fi internet. So Ive tried to connect the wires instead of wireless but the output of left rear doesnt work. I call the technical support and they said that this version doenst support wires for rear speakers only wireless and when I look up in the manual says the same.PS.I have no idea why only 1 speaker doesnt work when both of them suposed to dont work.Kinda system bug or locked feature permission?!
I was wondering if I can use the HT-TZ325 firmware which is the same version but doesnt support wireless only wires, to make it works.
If yes , How can I do it?Where can I get the firmware?
Another solution which I thought about is an update firmware version of my HT which gives me wires option or higher wireless frequency like 5.8 ghz instead of 2.8.
