Poor Wifi Connectivity

[JoeMeakin]

Wifi connectivity on my iPhone 5s has been terrible just latley.  The phone will only hold its connection for a  few minutes and when it is connected it is very slow.  Is this a fault with the new update?

I have tried re setting the router and ll that jazz...it doesn't help.  Other people in the house hold don't have an issue. (And they are not Vodafone customers btw)

Also,  I can hardly pickup 3G anywhere.  I was at work the other day and all my colleagues are with different network providers and they all get excellent coverage.  I literally have GPRS all day.

This seems to be something wrong with the network coverge as friends with the same plan as me are complaining of the same thing.  At this rate I will not be renewing my contract as it seems Vodafone are losing out massivley to other providers in terms of service and coverage.

Any advice?

There are a lot of complaints on the official Apple forums that the latest update has caused wifi problems, this is purely down to the update and not carrier related.

3G does seem to have deteriorated a lot over the past three weeks. In my area in Sussex my son has the same phone as I have but on O2 and he has a strong 3G signal whereas my 5s rarely picks up a 3G signal in the same area, and in the village where I actually live there has never been a 3G signal.
