R2 not updating firmware

[HRichie]

Hi guys, fairly new here and kinda useless with all this router stuff so please bear with me.

My R2 has a habit of disconnecting from the internet, and I realised my firmware is well out of date.

However when I try and update to the latest firmware, I just get the usual buffering icon and thats it.

I have included the file I believe is the latest update.

Any help or advice appreciated.
