RE AC1200 ADSL2+ modem router aka Archer D5. I'll have to check my profile etc to see if I can correct the information in the header.

First the good news, it is (so far) a vast improvement on my old BT Homehub2 in terms of signal strength and speed. It works nicely with my old, spare Win XP PC and with my wife's iPAD. Both channels and ethernet (no ethernet on the iPAD of course). Time will tell whether it solves my major dropout and slow service difficulties.

BUT with my Win 8.1 PC I have problems. I had a lot of trouble setting up - including IDtenT issues (!). I can now get ethernet and wireless on 2.4GHz, no evidence of a 5GHz channel. I cannot change the router password without losing the wireless connection so I am stuck on the original, weak one nb I can alter the password and the iPAD or Win XP hardware work well.

I have tried a load of things, I updated the firmware (9.1.0.4v 002e Build 140804) - reset, setting up again from scratch, changed cables, removed my AV and firewall, etc, etc.

I'm trying to exploit the manual but I'm not very wireless savvy so I could do with help.

Thanks

Sandy
