Intermittently slow speeds

Hi there,

Over the past couple of days I've been experiencing spotty/slow downstream speeds which is affecting youtube and general browsing. 1080p youtube videos only seem to buffer 10 seconds or so ahead and sometimes freeze midway through as if the connection temporarily drops.

Oddly this slowdown isn't reflected in speed tests and my tracerts seem relatively fine apart from a couple of timeouts. An example:

Tracing route to youtube.com [216.58.211.174]
over a maximum of 30 hops:

  1     *        2 ms     1 ms  routerlogin.net [192.168.0.1]
  2     *        *        *     Request timed out.
  3    11 ms    11 ms    15 ms  bmly-core-2a-xe-122-0.network.virginmedia.net [80.2.225.125]
  4     *        *        *     Request timed out.
  5     *       21 ms    17 ms  eislou2-ic-1-ae3-0.network.virginmedia.net [62.254.85.145]
  6    28 ms    21 ms    27 ms  6-14-250-212.static.virginm.net [212.250.14.6]
  7     *        *        *     Request timed out.
  8    25 ms    25 ms    20 ms  72.14.237.58
  9    23 ms    26 ms    27 ms  172.253.68.211
 10    25 ms    23 ms    23 ms  dub08s01-in-f14.1e100.net [216.58.211.174]

I've tried rebooting the router, changing wifi channels, moving the router, etc. Speeds still feel throttled.

Are there any known disruptions in the SW18 area?

Thanks

Re: Intermittently slow speeds

Sorry to bump my thread again but I'm still experiencing speed drops and this time I've got a better visual indicator of my problem.

Youtube's stats for nerds shows a connection that hovers around 3Mbps (lower than usual) and for some reason persistent activity drops and gaps in buffering. This results in videos freezing at various points.

spotty bandwidth performance also occurs on my tablet and other laptops so it's not isolated.

Re: Intermittently slow speeds

If you think that you have a BB speed problem, then to check the speeds coming in to your Hub properly, and whether they match what you should be getting, you cannot rely on wifi tests, you need to do it this way first.

Make sure your device has a gigabit network card and has the up to date drivers. Use a new Cat5e/6a ethernet cable (old ones do "go off") to connect it directly to the Hub - which you have put into modem mode (to ensure only your device is connected). Check speeds like that first - if they are still low - then, boot up your device into "safe mode with networking" (to disable any software on it that could be limiting speeds). Run the tests at speedtest.net (try on x2 VM servers) on 2 different browsers one of which is a fresh download of one you haven’t previously used (e.g. Firefox, Opera, Safari etc - there are several reports on here of certain browsers causing speed issues).
Try that and report back what you get.
