Infiinity II speed dropping over a few hours

[BillM24]

Hi all,

I had Infinity II installed about three weeks ago and when the technician was here it tested on BT's speed checker at 55Mb/s down, 17Mb/s up. After getting about 1.8Mb/s connection between home and BT before Infinity II, this was stunning! However, within a couple of days my download speed had dropped off to about 1Mb/s, so slower than it was before, and the upload speed was mirroring that quite closely. I did the troubleshooting and rebooted the shiny new homehub5 (homehub 4 before Infinity) and speeds increased again to about 48Mb/s down, 16Mb/s up. Within hours it had dropped back again to pitiful levels and if I leave it for 24 hours then it's pretty much unusable.

Just now ...

after I rebooted the hub about seven hours ago.

The connection speed between hub and BT has been dropping steadily. I'm guessing that because I have to reboot the homehub to get decent speeds for a while, the BT kit is assuming my line's unstable and is dropping the speed accordingly. Right now the hub's reporting 48Mb/s connection to BT, it was closer to 57Mb/s when it was installed.

Any suggestions?

Cheers,

Bill

Are you testing it with a wired ethernet connection or wifi?

[BillM24]

Only wifi. I've no devices with an Ethernet port.

Bill.

Chances are that Infinity is fine but there's some wifi interference affecting the transmission between the router and PC.

Can you post the line stats again the next time it slows down please?

[BillM24]

That's what I posted. Look at the speedtest graphic in the original post. I can reboot the router and run it again to show 46Mb/s down, 15Mb/s up.

Cheers,

Bill

Try turning off smart wireless then split the 2.4 and 5ghz networks giving each there selected channel number checking with a wifi analyser the best free channels. You can use same password.  You can then log into both networks assuming your devices are caoable of the 5ghz network

many devices have a probkem with the 2 networks combined

[BillM24]

2.4/5 already split, named differently, different passwords, no smart wifi, and I've worked my way through every channel over the last five days.

So these stats

6. Data Rate: 16560 / 49517

7. Maximum Data Rate: 14153 / 49513

8. Noise Margin: 4.4 / 5.6

are when you're seeing 1 or 2 Mbps on the speed test?
