lembab nih banyak punca.. pasal 1 mbps .. yang dia offer ko secara teori nya... 800kbps is an acceptable speed based on your speed quota request .. nak lagi laju request lagi banyak speed .. maka lagi banyak yang ko kena bayar..

memandangkan zaman wireless tech nih sume device guna network katakan dalam isi rumah ader 2 hp 1 pc dan 1 laptop.. sure akan jadi lembab pasal sume device nih sharing one connection.. if semua are connected to the internet.. lebih2 kalu buka youtube.. atau any streaming data.. sure akan brought all the network down [dalam umah lah].. atau slow cam jamban... nak tukar2 DNS .. aku rase.. cam tak der privisi.. pasal there is a posibility dia akan gunakan ko as a research hamster... cth usage ko terma pencarian ko.. etc2.. so aku tak selesa..

kalu nak tukar DNS aku tak galakan pasal baca bawah nih..;

"The recent rash of botnet [webmasterworld.com] issues has uncovered that the source of power for the latest and most widespread strain of malware is the free DNS servers being used to locate their command centers.
Why this is a problem is because these dynamic DNS services allow anyone to freely create a dynamic domain name such as "any-subdomain.example.com" which can be quickly and easily redirected to any new server when the previous botnet command and control center (C&C) is identified and blocked.

Botnets tend to have lots of infected machines that are idle, just waiting to be put into service, therefore closing one command center only shuts down the bot for a few minutes, perhaps even seconds, until the IP address is changed for "any-subdomain.example.com" to point to the next infected server now being used as the botnet C&C.

Best yet, the latest botnet strains have algorithms that allow them to detect new random subdomain names created so when "botnetsubdomain1.example.com" is removed from the free DNS service a new "botnetsubdomain2.example.com" is created, which the botnet can detect, and continues to run.

The names being used are completely randomized so it's not as simple as looking for something like "botnetsubdomain*.example.com" and blocking all variations as it's fairly undetectable.

Therefore, it seems a simple solution to eliminating this threat posed by free dynamic DNS services is to filter out the free variations of the dynamic domain names so that "any-subdomain.example.com" isn't accessible by anyone from a broadband service which would render the entire current variation of the Kraken botnet completely harmless.

So the question then is should broadband services, or all internet services for that matter, block these free dynamic DNS services in order to protect the safety of the internet as a whole and stop hundreds of thousands of machines from communication with their command center in one simple step?

I'd say YES, just like like ISPs currently use RBS to block spammers and known hosts of malware, that it's a reasonable step to providing internet-wide security against this latest and the most difficult to stop (to date) brand of botnet before more copycats emerge and the situation is completely out of control.

even kajian nih in 2008 but the risk is still there..

aku guna 20mbps unifi.. puas ati.. beb.. berbaloi baloi... nak rasa selamat wifi ko dari kena hack.. silalah sorok network id ko [SSID] guna password yang agak mustahil utok directory hack figure.. cth LaBu!@3!221#, guna WPA2PSK format

IMHO

1. dekat kan laptop ngan router>>kalau internet makin laju maknanya router problem.

2. nak test connection,try direct modem(yang kaler biru gelap tu) trus g laptop jgn pakai router. then kalau pakai direct modem pun still slow, mmg dah bole shoot 100.

3. punca line slow ada banyak
a)cable bawah tanah tu..
b)mmg ada haiwan perosak yang kacau cable
c)cable LAN tu (majoriti lepas tukar kabel dah ok)
d)cuaca kita

lepas call TM, technician akan datang mai rumah wat inspection dan akan advice apa patut buat.

regards.
