Neotel network speed degradation update

OK..NEOTEL!

I would now like the NEOTEL rep here to pass the following on to their Network Engineers to look at...and then, tell me again you are not limiting our bandwith!!!!

WEB100 Enabled Statistics:
Checking for Middleboxes . . . . . . . . . . . . . . . . . . Done
checking for firewalls . . . . . . . . . . . . . . . . . . . Done
running 10s outbound test (client-to-server [C2S]) . . . . . 965.0kb/s
running 10s inbound test (server-to-client [S2C]) . . . . . . 65.40kb/s

------ Client System Details ------
OS data: Name = Mac OS X, Architecture = i386, Version = 10.5.6
Java data: Vendor = Apple Inc., Version = 1.5.0_16

------ Web100 Detailed Analysis ------
10 Mbps Ethernet link found.
Link set to Full Duplex mode
Information: throughput is limited by ISP
Good network cable(s) found
Normal duplex operation found.

Web100 reports the Round trip time = 464.65 msec; the Packet size = 1448 Bytes; and
There were 3 packets retransmitted, 17 duplicate acks received, and 17 SACK blocks received
The connection was idle 0 seconds (0%) of the time
S2C throughput test: Packet queuing detected: 50.45%
This connection is network limited 99.41% of the time.
Excessive packet loss is impacting your performance.

Web100 reports TCP negotiated the optional Performance Settings to:
RFC 2018 Selective Acknowledgment: ON
RFC 896 Nagle Algorithm: ON
RFC 3168 Explicit Congestion Notification: OFF
RFC 1323 Time Stamping: ON
RFC 1323 Window Scaling: ON

Information: Network Middlebox is modifying MSS variable
Server IP addresses are preserved End-to-End
Information: Network Address Translation (NAT) box is modifying the Client's IP address
Server says [41.174.xxx.xxx] but Client says [192.xxx.xxx.xxx]



And some more info to prove the above.....

The theoretical network limit is 0.13 Mbps
The NDT server has a 127.0 KByte buffer which limits the throughput to 1.30 Mbps
Your PC/Workstation has a 511.0 KByte buffer which limits the throughput to 8.60 Mbps
The network based flow control limits the throughput to 0.14 Mbps

Client Data reports link is 'Ethernet', Client Acks report link is 'T1'
Server Data reports link is 'T1', Server Acks report link is 'Dial-up'

Awaiting a meaningful answer.....
 
South African companies are always out to screw their clients - just a fact.
I've had Neotel for 4 months and never reached more than 56k speed - pathetic.

Their support are a bunch of idiots that does not even posses the basic network knowledge. They read from already prepared tech notes so sometimes you get treated as a novice and totally ignorant of PC tech. - I design corporate networks so these guys cant even understand me when I start.
I'm now out of this country for the UK, cant wait to have proper broadband service.
F*** SA ISP's

Thanks Valken, very useful.
It is as I suspected for these past 10 months - our bandwidth IS DEFINITELY being limited.
This, amongst many other reasons (see my post http://mybroadband.co.za/vb/showthread.php?t=160309&page=3 ) is why I have cancelled my contract with Neotel due to non performance from Neotel's side.
Today will be 17 days since I first notified Neotel of my cancellation and they have still not come back to me regarding the payment issue of the hardware device for the remaining period of my 24 month contract (I have sent numerous emails requesting clarification on this as well as visiting their offices in Woodmead, all to no avail).
I cannot wait for them to insist I pay R80.00 per month for the handset for the remaining contract period; me smells a fat lawsuit coming up from my side

Whatever they've done (if anything) this evening, it's made no difference at all.

As usual.
 
Hi all, in majority of the cases the speed issue should have been resolved.

However should this not be the case in a particular area; we have a second set of optimisation tasks to complete.

A schedule of when this will done will be published in order of priority over the next few days.

In the interim please continue to provide feedback in the format that PeteGT has been doing - it is appreciated and helps to optimise (further) where necessary.

@ abraxis: I have your details and will contact you tomorrow to give you an update - you are on a priority list for resolution.
@ Valken: Thank you for the rant and the info, I will pass the info onto the engineering team even though you have indicated in another thread that all is restored.

Thanks Neotel...

Yes, things seems to be a lot better! Will check again tomorrow and see how it goes..

@ busker: More optimisation is planned for Cape Town.
 
There's definitely been an improvement since last night:

Unfortunately no resolution yet for me. My connection isn't any better than it was. Parktown, Johannesburg. My connection works for about 5 mins at a time then stops responding altogether. To get it working again I either have to wait for a long time, or reset my modem or turn it off and on. After that the connection functions normally for 5-10 mins before completely ceasing to work yet again. Last RSSI I had was 79, haven't been able to open Axessmanager again seeing as it takes forever. Speed and ping all operate within normal parameters until it suddenly stops working.

You asked me to let you know if I had improvement after last night.

Nope... I checked my downloads this morning and my 'past' few hours 'history' and it only did 20/30KB/s all night.
 
@ JMRHOWES:

As discussed with the Ops Manager we are looking into your issue.
 
We have not been using Neotel NeoFlex for some time in the office, but using it again today and the service is not bad…

Shoo not bad.

*Waiting for my Neoflex to kick in as of next month*;)
