Serious browsing speed issues.

Safari and Firefox.

I cannot open www.macsales.com (server not found) and speeds to other sites are very poor. I have a 15Mbs line, but my old 27" iMac shows 754Kbps on Snow Leopard and My Mavericks 5,2 Mini shows 1-4Mbps. (speed upload)

The ISP engineer came and the site opened on his PC laptop just fine and he did various line speed tests that suggested 16-20Mbps to servers in the Eastern USA. Ping was poor at +-250Ms.

So, everything indicates that this is an issue with my two Macs.

Any ideas please anyone?

TIA.

Can you tell us about your router (if you have one), or any switches or other network devices you might have (if you do)?

Are your two Macs connected via typical wired ethernet (for example 1000BaseT), or wirelessly, or by some other method?

Can we see the results of the following commands copy/pasted into your Terminal on either of your Macs?

Code:

ping -c 3 tot.co.th

ping -c 3 google.com

traceroute tot.co.th

traceroute google.com

ifconfig

cat /etc/resolv.conf

echo "done"

Ok, the router is a Cisco EPC2425. Actually, it's labelled as "Modem only, 4 port wifi" now I look more closely. Does that mean I have no router at all?

Currently, the Mini is plugged into the ethernet cable and the old iMac is on wifi.

No other hardware in use at this time.

How long should I leave it running?

The last "operation is currently numbered 46 (and climbing) followed by 3 asterisks?

Here comes a bollocking for a mega paste job:

One explanation when you have a super-slow ping time on the first packet and a normal ping time on the second packet is that you have a problem with your DNS lookup, perhaps where the first-listed DNS server is not working properly, so that eventually times out and your system checks the second-listed DNS server, which returns a result.

We could check that somewhat with the following pings, which don't require DNS lookup, since they're pinging IP addresses:

ping -c 3 203.114.102.100
ping -c 3 113.21.241.35

If those pings all come back quickly, that's good evidence of DNS issues.

Gavins-Mac-mini:~ gbmm2011$ cat /etc/resolv.conf

nameserver 203.144.206.29

If I ping both of those DNS servers, I get nothing:

Code:

It's possible that I just can't use them because they only allow use from your ISP's addresses or something. Can you ping those also, and see what results you get?

OK, the problem continues when pinging IP addresses, so it looks like it's probably not DNS. But you have something that makes initial packets super slow and later packets move normally.

I'm not sure what it might be, but I'd certainly look closely at your Cisco EPC2425. I don't think it's related to operating system on your computers, although if you could repeat those pings from a non-OSX box that would be better evidence.

Trevor

I have a Cisco E3200 dual band router from when I lived down south - could I replace the ISP supplied Cisco with that?

Or does it need a separate modem? Sorry I'm really useless with networking/similar kit.

No current access to a PC unfortunately.

Trevor is helping well:) As always.

I would go with http://www.opendns.com that can make a difference for many things.

You can set opendns per computer or at the router. I prefer the router set it once and done. Does sometimes take longer to figure it out router end. Open DNS provides directions. Switching routers may help. Using ISP cable modem and your router is usually not an issue.

On a side note I tried to embed as I have many times on this website subpages from macsales and got some weird behavior regarding resolving when linked from this forum. Odd.

Yep, Trevor is a rock!

Having checked, the router is locked down, so I can't adjust anything. Anyone know a way around this?

Try from the computer first?

Any Dummies guides to setting up my E3200? I did it a couple of years ago, but my memory of that is a gmf.

It may be worth noting that my iOS devices can't get the owc page either, although they can on 3G. Does that offer any insights?

Cisco E3200 info at the Linksys web site: http://support.linksys.com/en-us/support/routers/E3200

Many thanks. So, do I need a separate modem then? I'll read that when I get home in an hour, but I'm driving at the moment. If i do need a separate modem, any recommendations?

OK, done some of that reading now.

So, if I want to replace the ISP-supplied modem, is their a "best" model that I should go for as the replacement? Recommendations appreciated.

I think I would start with opendns. Try the wired mac first and use the computer side settings and see how it goes.

Normally unless there is something wrong with the cable modem, which in your case seems to have multiple ethernet and wifi you do not replace it. You just turn off wifi and use your own router and or switch with it.

If it did have to be replaced usually one tries to work with their ISP to request a replacement. Cable modems are less common but can be purchased but ISPs sometimes do not make it easy, and it can effect there remote trouble shooting.

Well done that man!

Sorted.

To help me "try" and understand then, were the ISP default DNS settings perhaps too Windows friendly then, assuming that's even possible?

In case it is of any relevance, browsing is noticeably faster too.

Some ISP DNS servers are just crap ! Just the way of the world of Tech.
TBH in business we use our own internal DNS servers that query externally and cache info locally. All very fast ;-)

OK, but why did the ISP engineer's PC have no problem then? I can't get my head around that.

They could have been using there own dns too, perhaps even opendns.

Good point, but knowing the natives as I do, I doubt! ;-)

Could be a corporate image for their laptops with a different DNS. In fact it could even be part of broader set up. Is the net filtered there like it is in some places?

Filtered? Is that the same as censored?

Yes ...

http://en.wikipedia.org/wiki/Interne...ip_in_Thailand

small excerpt...

Censorship of the Internet in Thailand is currently for website access only. Unlike China's “Great Firewall”, which censors all Internet traffic including chat conversation via Instant Messaging, Thai Internet users are still able to interact with other users without being censored. However, current policy is to use a system of transparent proxies so that the user receives system, server, TCP and browser error messages when trying to access blocked sites leading the user to believe that the failure is caused in the Internet itself.

http://en.wikipedia.org/wiki/Interne...ublic_of_China

Included a wiki for China to because it includes many other methodology which I thought was interesting.

Is it a TOT router? If it is, the username is admin and the password is tot.
If that doesn't work, you can hit the reset button and reconfigure the router. after you reset it, it will ask for an authentication login to authenticate into the TOT network, usually the username to login to the Internet (not login to the router) is yourphonenumber@tothome, and the password is yourphonenumber, but you should check with the service provider, or if you're in a rental house, check with your landlord.

Someone hacked my router once while I was in Thailand. I just reset the router and used homephone@tothome to login again.

No, it's a True-supplied POS.
