So my wife called to say there’s no WiFi upstairs. Rushed home to fix up as she’s working. Get there and immediately spot that the cable has broken right at the plugs end. Great let me just cut and add a new plug. Crimped and 5 mins later up and running. For some reason I decided to do a speed test and notice that it’s only getting 112mbps (max out of about 10 tests). Go downstairs and speeds are high as per normal. Change the AP’s and same thing, still slow upstairs where she works.

Nothing has changed at all besides the cable which had that break in it from being moved. Any other ideas as to what the issue could be?

Is there a knot in the LAN cable?

Not that I can see. Will have to climb up in the ceiling when I get the time.

Tried connecting another cable to the router with the same AP, works like a bomb. Tried changing ports with the upstairs cable, same issue. Definitely the cable that’s the issue. Seems like I have to run a new cable sometime
 
Also think I need to just fit a unifi in there. I’ve been using a MikroTik router think we might need to plug in a cable for something in future... future has come and never needed to do that. The unifi will resolve the issue of cable breaks as well since there’ll be no need to move it.
 
I can definitely vouch for Unifi; I am running them in my house and have never had an issue (touch wood).

They aren't as 'plug and play' as other solutions, but once set up they are very robust and have nice features for the price.
 
There's 8 wires in a LAN cable to give you 100/1000MBs
If 1 strand snaps you effectively only run at 10MBs

This was my experience decades ago in the IT industry, not sure if it is still the same nowadays. @Thor pulls wire through ceilings all day every day so maybe he can verify
 
No need to try and sell me on unifi, I know all about them and deal with them quite often... in fact you’ll notice I’ve sold quite a few of them to members here as well.

which reminds me I’ve got some that I need to collect for members.

The consensus then, is the following:

 
Very likely though that a wire could be broken inside the cable somewhere due to movement. Will just replace the entire cable when I get a chance the weekend.
 
@PhireSide definitely going to add the unifi. Will get rid of the issue of wire breaking in future... in less of course someone thinks they can hang on the unifi haha

Not impossible at all - do you have a tester to confirm continuity on all four pairs?

112mbps is around 14MB/sec, so theoretically it's not running at 100FDX. There is the possibility of a portion of the cable being damaged and this could be causing a high retransmit rate.
 
I am in Somerset West, on openserve, afrihost, and my internet just tanked. Browsers are not loading properly. My husband says internet on his side also laggy. Is there a national issue we should know about? My net died at 12oclock last night, don't know when it went on again during morning hours

I assume you have already re crimped that new end?

Unfortunately no tester, but the spare cable proved that it’s a cable issue.

I do not, but my brother in law and mother in law stay that side.

Ah, my bad. I was going to say that I stayed in one of the double-story townhouses there and I only had the router (that comes with the house) in the garage which covered the entire house
