My brother has a Thomson TG585 router supplied back in the day by Plusnet. I'm told it says version 8 software 8.2.7.8. Is there a way to un-plusnet it, turn off the ADSL bit and make it work nicely alongside (well a long CAT5 cable away) another router to boost the woeful wifi in an older house? On client devices, it just takes you to the Thomson web interface and wants a signs in, and the DSL is down (we know that - it's not plugged into the Thomson!)
Is it landfill fodder or is a re-flash doable?
