Bug Description

Has trouble finding my router wifi. Sometimes finds my neighbour's but not mine. Others do not have this problem. Advice in Help sometimes works to connect.
When found, the connection 'arcs' icon shows a connection but then changes to the double arrow logo (usually associated with wire connection).
Currently connected but showing double arrow. Drop-down menu shows no available wifi's.

It appears you have:

  Intel Corporation Centrino Ultimate-N 6300

using the iwlwifi kernel module, so reassigning to the kernel.

Also, please try moving the laptop close to the router. Does the problem go away?

I've noticed HP laptops sometimes have particularly weak wifi reception.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.18 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.
