TP-Link TD-8816 ADSL2/2+ Ethernet Router

Today I grabbed another modem router for testing in my ADSL line.TP-Link is No.1 market share holder in China and has been a global player in the market.The product is quite cheap compared to D-Link or Linksys,however,the comments are quite positive.

TP-Link TD-8816 TP-Link TD-8816 is said to have TrendChip inside.Through the past testing period,I found the heat from this stuff is less than D-Link DSL2542B.However,it shows higher line attenuation and lower SNR margin compared to the D-Link modem.Perhaps it approves some hearsay that Broadcom chipset could get better result on a bad quality line whereas TrendChip chipset could sync faster and stable at a good quality line.

However,if you ask me which one I will choose,TP-Link will be my choice.Well,at least it allows me to manually connect/disconnect on the web-based control panel(ie. get a new IP address and minimizes the possibility of overheat issue.

Let me sum it up:TP-Link sells goods with a cheaper price,but the quality is not cheap at all.

I just bought a new ADSL2+ modem today-D-link DSL2542B.

My ADSL line(Streamyx) quality is not good because of the bad copper connecting between the cabinet and DSLAM.Thus,the free modem given by TM-Billion 5112S can’t get a stable connection always.I googled a lot to dig out how to get a low line attenuation and high SNR margin to achieve a much steady online experience and I found that the modems which are built with Broadcom chipset normally could gain a good result on a bad condition.That’s the reason why I choose this modem.

I have to say that it does work well at current condition.Here’s the ADSL information from the modem:

D-link modem status The downstream SNR margin shows consistently at 28-29db whereas the downstream line attenuation becomes at 43.5db,slightly lower than before.

The TM technician who I’m familiar with is still looking for a way to let me have a better line attenuation in order to fulfill the requirements applying to upgrade to 4Mbps.I wish that will be a way indeed.

Through doing the settings and testing,I met some questions and didn’t solve yet.

  • I can’t get it work once I set this modem at bridge mode connecting with Linksys WRT54GL router.
  • It seems like only auto connection could be done in the modem.I can’t manually connect or disconnect one session.

Anybody has solutions?

Tomato 1.25

I applied Tomato firmware since I started to use Linksys WRT54GL.It is customized from the original firmware and designed to be more functional and stable.

Router List The latest version Tomato 1.25 was released several days ago.It fixed one major problem on the previous Tomato 1.24.The changes since Tomato 1.23 are:

Version 1.25

  • Fixed WL MAC address may not be set properly. This seems to have caused various connectivity problems, including a possibility of getting locked out.

Version 1.24

  • Fixed static IP entry was ignored if it exceeded a certain length even though the GUI allowed it.
  • Fixed Device List may not display Static IP hostnames.
  • miniupnpd replaces the older UPnP service, adds NAT-PMP support (must enable).
  • Added options for DDNS refresh time and do not perform an ‘NVRAM commit’ for DynDNS in the GUI.
  • Added ID for WTR54GS, WZR-G108 – thanks to BaoWeiQuan; WR100 – thanks to Hovsep.
  • Various fixes, WL500GP, WL520GU, WBR2G54 – thanks to Fedor.
  • Added options for more SSH/telnet connect limits in Admin:Access.
  • Added option to use WAN port for LAN in Basic:network.
  • Reworked logout. Tested with IE, FF, Safari, Opera, Chrome.
  • Updated Busybox 1.14.0, Dnsmasq 2.47, L7 filters 20090510.
  • etc.

If you have a proper model of router,just try to install this firmware on and I’m sure that you’ll definitely like it later. :)

Linksys WRT54GL V1.1

I bought Linksys WRT54GL years ago which previously worked with an Aztech modem.After the modem broke,the router was put into a corner as I had Linksys WAG200G modem router,acting well on normal use.

However,recently I’m heavy downloading and it makes the transmission congested once several PCs are using at the same time.I think putting the router into the network should be a good solution as I could do some QoS(Quality of Service) settings there so that optimize the entire network.

This router packs with Broadcom BCM5325 200MHZ CPU,16MB RAM and 4MB flash and it is set on Linux-based,so lots of third-party firmware which may boost the performance are available,such as DD-WRT,Tomato,Open-WRT etc.The official ‘stock’ firmware just means stable for normal use.For me,a DD-WRT or Tomato firmware would only fit my needs.

Steps to install DD-WRT firmware:

  1. Turn the router into default settings(stock firmware)
  2. Upgrade to DD-WRT mini firmware and reset
  3. Upgrade to DD-WRT standard/VPN/VOIP firmware and reset
  4. Configuration

After I flashed the new firmware,I started P2P downloading as a test.I used QoS setting allowing 60% of bandwidth for P2P downloading and 40% for HTTP and others.I’m not quite satisfied with the result because it still made the network congested;in addition,the interface loads very slow.Thus,I decided to try Tomato firmware immediately.

Steps to install Tomato firmware(directly from DD-WRT V24SP1):

  1. Turn the router into default settings(of DD-WRT)
  2. Upgrade to Tomato firmware and reset
  3. Configuration

It’s a very simple trilogy.The interface is very clean so that setup will never be a tough thing.Ajax technology makes the interface load very fast and consistent.What is important is that no more congestions while heavy loading.Awesome!

From now on,I will be able to fully utilised the bandwidth of DSL broadband without annoying.Happy day! :D

Linksys WAG200G

What is it?That’s it!!!

side face…front…

It’s my new ADSL modem.Actually previous one is from linksys as well and still can work if I send it to flash its firmware,but it may spend some weeks so that buying a new one is a better choice and make that old one as spare.

Linksys(which is under Cisco)  is one famous brand in this scope.It provides good quality and service so that I have confidence on its production,even it is some more expensive.

Look at it…It’s designed as normal but those assemblies makes quite exquisite.And when I connected all cables and inserted default CD for further settings,I’m surprised that all steps were made by simply clicks and some easy type-ins and at the same time almost all useful functions are still there.It’s quite suitable for those high demand and entry -level people…

Another point is you can make a instant way through its official website to gain your immediate information to solve any kind of problems 24/7.After my explanation,what do you think about it?Hahahaha…Big thumb,right?! :)
