I'm a newbie to OpenWRT, LEDE and LUCI, though I've used Tomato on a WRT54GL for many years. I've installed David's lede-mvebu-cortexa9-linksys-wrt1200ac-squashfs-factory.img - and I am really, really impressed! Thank-you to everyone who has contributed.
I have been trying to set up a guest wifi using the instructions here: https://openwrt.org/docs/guide-user/network/wifi/guestwifi/guest-wlan-webinterface
However, when I come to configure my firewall zone settings, LUCI does not display the tick boxes for 'masquerading', for 'MSS clamping', nor the edit and delete buttons. These are shown on the guide, but not on my LUCI - it looks as though the page has cut off just towards the right of the 'Forward' column, and I cannot scroll across to see the missing fields.
Can anyone explain why this is?? And how do I fix it??
I'm using the current version of Chrome, but have tried Edge and Internet Explorer under Windows10. All have the same issue. I can post a screen grab if it would help?
If I'm being a complete idiot - then please accept my apologies - but this is driving me insane and any help would be gratefully received.
