Erratic Internet Speed Causing Connection Problems

Question

Hi BTCare,
I have been a BT Broadband Customer for many years and haven't faced any difficulties up until a week ago; I have the original white home hub. In June 2010 an ADSL upgrade was carried out in my area and since that time I have been able to achieve 10mb Broadband speed consistently (Peak & Non-Peak) without any problems.
In the past 5-7 days my Internet Speed has been slowly deteriorating and is now becoming almost un-usable. Earlier in the week the speed dropped to around 5mb and I contacted BT Support over the phone and they instructed me to run speed tests throughout the day suggesting that the problem may lie with internet activity in my area increasing during peak times. This didn't seem to be the case as the speed tests were returning similar speeds regardless of what time of day I carried out the tests.
Since then my speeds have continued to decline to as low as 1mb at times which has now made it difficult to even use the internet as even loading web pages sometimes takes up to 30 seconds. Some wireless devices (e.g. iPhone) can't even establish a connection to the router even when I am standing directly in front of it.
I have configured my wireless connection (changing channels etc.); re-starting the router at intervals hoping this will improve matters but this has proved fruitless. I have run a speed test now with the results as follows:
 Download speedachieved during the test was - 240 Kbps
 For your connection, the acceptable range of speedsis 100-500 Kbps.
 Additional Information:
 Your DSL Connection Rate :5923 Kbps(DOWN-STREAM), 1191 Kbps(UP-STREAM)
 IP Profile for your line is - 500 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 8.84:23.63:67.79 (SBE:NBEBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.
The results of this test will vary depending on the way your ISP has decided to use these traffic classes.
Upload speed achieved during the test was - 171 Kbps
 Additional Information:
 Upstream Rate IP profile on your line is - 1191 Kbps
Any support you can provide will be greatly appreciated.
Kind Regards,
Dan
