The current modem and thus WiFi at my mums house is pretty much in the middle of a long narrow house,

Was thinking to run some cat6 from the current modem to kitchen end of the house. , then expand from there

Should i be using 568A to terminate and do i terminate all the pairs of cable?

Are all the cable in the pictures now useless and i could get rid off and use a pull cables?

thanks

There is insufficient information to answer your question.

If you have moved to fibre or a wireless service and no longer have a landline, then these cables are redundant. If you are using xDSL, then no, these may still be required.

As for terminating cables, you should terminate solid core cable on keystone jacks and plug cables into those. You will either need a punch down tool or tool-less keystones. 568A or B are fine, just make sure you use the same at both ends.

Note that those phone cables were often stapled in the walls so might not be useful as pull cables. But sounds like you've got nothing to lose if they aren't in use anymore.

Also chances are the holes through the studs are not large enough for Cat6 cable

He does need to be a bit careful thou,

A fallback position is to use the existing cable (likely cat 5 or some other 2 pair variant) to run a 100mbs connection, -

Most people want to run ethernet and not buy other gear to make it work.

If its 2 pairs, you might be able to get 100mbit across it.

If its cat5e and that blue cable will almost certainly be at least cat5e, then its capable of 2.5gbit up to 100 metres, 5gbit up to 40 metres and 10gbit up to 30 metres.

The 2.5gbit standard was designed to fit within the unused spectrum of a cat5e cable.

If its cat6 then its capable of 5gbit up to 100 metres and 10gbit up to 60 metres.

Please post higher quality images so we can give further advice.

I have since realsized I need to dig deeper as the house alarm could be wired into this mess somewhere too.

I may end up just running new cat6 after all .

The alarm feed is most likely that blue cable then as it probably came later and the original phone cable is the white 2 pair.
