Help! Really stuck as to what is causing drop in speeds...

[john46]

it is worth a try

[toonlass]

I have borrowed a corded phone and there is now silence on the line - anything else I can try?

Thank you

[john46]

no that is all you can do when the speed drops again please run the BT speed test again and post the results

[toonlass]

The speed has again dropped from waking up this morning - unable to stream content and even slow to load this website.

I have completed a wired test:

 Best Effort Test:  -provides background information.

	Download  Speed
	3.79 Mbps

0 Mbps

7.15 Mbps Max Achievable Speed

 Download speedachieved during the test was - 3.79 Mbps
 For your connection, the acceptable range of speeds is 0.6 Mbps-7.15 Mbps.
 Additional Information:
 Your DSL Connection Rate :5.54 Mbps(DOWN-STREAM), 0.45 Mbps(UP-STREAM)
 IP Profile for your line is - 4.5 Mbps

and my router stats (iMac for wired test LAN4)

Once again the wholesale test wired on my iMac seems to be telling me that speeds are 3.8mbps, but i feel this is inaccurate when pages are slow to load etc.  Using other speedtests on iOS devices i get 0.5mbps and under - so same issue as before.   I installed replacement microfilters over the weekend too.  We were getting 3.9mbps even at 2am! Any idea gratefully recieved as this is still a mystery to me! Thank you

[john46]

The BT Wholesale speedtest is accurate wireless speedtests are not accurate due to external interference
your router stats looks ok as well

[toonlass]

So what could be stopping my wireles devices being able to stream TV etc?  Over the past few days when the wired wholesale test said 3.8mbps I was also getting htis on my wireles devices.  I have not changed anything.

[john46]

have you tried changing the hubs wireless channel
also not sure what you mean by getting hits on your wireless devices

[toonlass]

Sorry i meant 'this' not 'hits!'

I have tried changing channels - I also ran a diagnostic on my iMac to tell me which was the best channel to use.

[john46]

Unfortunately wireless is prone to interference from multiple sources not just other router or home hubs and therefore less reliable

[toonlass]

Still a low speed today on all devices.  We have no neighbours to have any inteference from their routers.  I have had our cordless phone switched off all day.

When I do the wholesale test wirelessly on my iMac it still gives a good speed (2.7-3.8mbps).  Any ideas why this is this not reflected through other wireless devices?

Is it worth changing the DNS server?

Thank you
