Fast Connection Speed - But Some Websites Don't Load Properly

Rik · Oct 08, 2009, 19:31:17

Very few routers are gigabit, Robbo, possibly the new N Netgear, but I'm not sure. What happens if you do a BT speed test (not sure if you can from a Mac, so if not, try speedtest.net and use the Maidenhead server). You could, of course, be describing an overloaded server at the BBC, BT or IDNet congestion or an issue with your setup, so the first thing to do is to establish what a speed test can tell us.

Are you on Max or WBC, and if Max, which package?

- I didn't get the option for that server so I picked Milton Keynes

When I actually access a web page, the speed is pretty good!

I am on Max on the 30GB package

What are your current router stats: downstream sync speed, noise margin and line attenuation? It looks like you're on a 4.5M profile from that test (MK and Maidenhead seem to return similar speeds which, for me at least, match the BT test closely enough).

BT speedtest is ok on Mac with Safari (when its not busy) I have seen the reset of MTU back to automatic mentioned in Apple discussions with SL. However the manual setting does seem to stick on my unibody MB I by the way have no issues with iplayer via Safari on the MB.

With regard to routers I personally would ignore the gigabit as they tend to fetch a premium,if you configure your network so the router is just doing its dhcp/nat bit and then link the other wired components together through a separate gigabit switch.

The dual band wireless routers seem a good idea as you can separate your N stuff from the rest i.e I connect my MB to the 5GHZ band at 300Mbits/s .If I connect to the 2.5GHz band I can get N speeds only if there is no "g" traffic.

Thanks, Steve.

The upcoming Netgear DGND3300 doesn't have Gigabit ports, the only one I know of is the Billion BiPAC 7800N, but it's not exactly cheap.

I have just done another speed check which comes out a bit better:

I do usually get higher than 5Mbps to be honest.

Point taken regarding the gigabit switch, I will drop that requirement.

Thanks all for the continued help

I am not sure if this helps, but I have also run a ping test (a beta application from the speed test website). The results are here:

I have run a number of tests and the results are always quite bad, with high packet loss and poor ping. Could this be linked to the problem?

Thanks

I also get 100% packet loss unless I turn off SIP ALG in the WAN settings of the Netgear dg834N using Safari on MB. Don't ask why or what as I don't know

robbo1 · Oct 08, 2009, 20:34:29

Fair play, at least this isn't all completely confusing then!

There is a few up dates on this page http://www.3com.com/swd/jsp/user/result.jsp?selected=all&sort=effdt&order=desc&sku=3CRWDR100A-72 if its any use.There is a firmware there from 2007 Have you tired turning the router firewall off temporarily?

robbo1 · Oct 08, 2009, 22:30:28

Thanks Stevethegas, already got the latest firmware loaded.

I will try turning off the firewall tomorrow and see if it improves things.

Cheers
