High Latency from surfing local websites since upgrading from 25mbps to 100M Cable Plan.

High Latency from surfing local websites since upgrading from 25mbps to 100M Cable Plan.

Hi,

 

Since uprading my plan to the 100mbps cable plan (modem was changed) , the latency for websites isannoyingly high. It is sometimes fast, sometimes slow. Wired connection directly to the cisco modem/router. It feels slower before upgrading which is extremely dissapointing.

 

Any ideas on how to slow this problem?

How about some traceroutes to start with?

Re: High Latency from surfing local websites since upgrading from 25mbps to 100M Cable Plan.

denilson isnt the only one with this issue, many of us are having this F**Ked up 100mbps cable service. Helpdesk asks me to send screenshots, proving the high latency and do stuff like NBTSTAT. Still no conclusive answer. I even got my DLINK modem changed ONCE and cable connection resetted ONCE.

 

The helpdesk people Wayu and Henry took my case, the latter promised me level 2 support will look into it but still no response. Let me remind you that this issue surfaced recently with the upgrade from 25mbps to 100mbps. I rather NOT UPGRADE if i knew of this high latency issue.

 

You support people listen up and get your network engineers to get their routing paths/DNS/whatever fixed. Having 100mbps cable latency speeds worse than Malaysia's ADSL 10mbps is nothing short of mockery for an ISP of Starhub's caliber.

Re: High Latency from surfing local websites since upgrading from 25mbps to 100M Cable Plan.

Ok, I managed to solve the problem by disabling TCP IPv6 on all computers. sieow13 you might want to try that to see if it helps.

 

There is some problem with IPv6 stack on the 100m cable plan with the Cisco DPC3925 modem. Using chrome, the status on the browser ( shown at the bottom on the brower page), would show resolving host for very long.

 

My friend's house with the 150mb starhub fibre plan seems fine with IPv6 enabled, she was using the d-link DVG-N5402SP modem. 

 

In the network connection details, on the cable plan, the computer would show IPv6 Dns IPs but no IPv6 default gateway IP. On the fibre plan, the computer would show IPv6 would show no IPv6 Dns IPs but show IPv6 default gateway IP.

 

Anyway this is the tracert on the computer before disabling IPv6

So anyway I read that disabling TCP IPv6 is not a good long term solution, is there anyway of solving this problem without disabling IPv6? 

 

According to this article below, he says:

 

When you have a network problem that is “solved” by disabling IPv6, you have masked the symptom of a bigger problem that warrants further investigation.

What was resolved after you disable IPv6?

- Latency to local site?

- Accessing local site?

I've disabled IPV6 from all PCs and it didnt improve my situation at all. High latency spikes still occur. Using the DLINK modem connected to my ASUS N66U. Weird to my modem directly still the same. End of day 1 and still no starhub personnel contacted me after being promised by their helpdesk. This is a backend problem. And its HUGE.

@sieow13 Please let me know if the technical team has not contacted you by 12pm.

Latency to surfing websites both locally and internationally.

@denilson

So can I say the 'latency to surfing' is pertaining to browser loading speed of the site, and not based on traceroute?
