Electrical timer for network router

31/12/2016 Leave a comment

I did explain in an earlier post about how useful these electric timers are. In August, I faced an issue with one of my clients. They had a system that needed to be rebooted periodically or that system would “hang”. The devices were an AV switcher and a network router. That is the problem with these network routers…especially the consumer grade ones that cost less than $100. They will hang and need to be re-started periodically. So what I proposed was to go to the supermarket, buy a couple of these (they only cost about $10 each) and install them in the client’s premises. After I did that, I did not receive anymore calls. I set the timer to turn off the equipment at 0200 hrs and come on at 0600 hrs. So if you are looking for a solution, which is relatively inexpensive, this will help

Faulty power adapter from my Linksys WRT54GC router

02/09/2016 1 comment

This is a picture of the adapter that came with my Linksys WRT54GC router, the one that I had since December 2007. This router gave sterling performance until I retired it some time back. I noticed that the adapter was always wet and it was not because of water. Something must have been leaking out of it. It could have been electrolyte or something else because to be honest, one ting I notice about Linksys and their adapters of old is that they tend to get pretty hot and so, something for sure is going to get “baked” inside it. Yes, I jest you not…they get too hot to touch!

So a couple of weeks back when my main router died, I dug this out of storage and used it. I had no other choice as I had no router in the house. Boy, talk about a bad move. My router died and it was due to the bad adapter. Now I have a problem. I have a perfectly good router but no power supply. And the power supply has a weird voltage rating too… 3.3 volts DC! But I love this router and I am going to keep it. I just need to find an adapter.

Upgrading firmware on TP-LINK TL-MR3020

08/01/2016 Leave a comment

Sometimes, I go against what I preach. I have said in many a post that I always will NOT upgrade firmware on my devices. But sometimes, my own advice falls on deaf ears. This is what happened.

As you all probably know, I have this gem of a router, the TP-LINK MR3020 that I like very much and has saved me many a time. I have used it with absolutely NO issues with my Huawei E1550 HSDPA dongle. Now a couple of years back, when I re-contracted with my service provider, they “gave” me a new dongle, a Huawei e3131. That Huawei dongle does not work with my MR3020 and the router does not detect it. So what do I do? First of all, I go to TP-LINK’s website to download the modem config files so that the router will recognise the e3131 modem. I tried a few but they did not work. So I look at the new Huawei e3131 and I look at my old Huawei e1550 and tell myself: it is time for a firmware upgrade for the TL-MR3020

So I go to TP-Link’s website and download the firmware for the modem. I download it and install it. After that, the router reboots itself and presents me with a new login screen. I try to login and can you believe it? I am bloody locked out! I tried the default username and password, I tried the old username and password (old passwords do NOT work on newly-firmware-flashed modems) to see if it would work but no go. So after kicking myself, I fired up the internet and went to look for a solution. I came across this article written by someone who advised to use Opera or another browser to login. I cannot believe it. It was something so simple and THAT WAS THE ANSWER! So I fire up Opera and thank heavens, the default username and password worked!

So I login to the router, checking what has changed and what had not and then came the moment of truth. Would this Huawei HSDPA dongle work on this newly flashed router? Well, I unplug the power, plug in the Huawei e3131 and would you believe it? The bloody thing would NOT work! Fucking hell. But then again, nothing ventured, nothing gained. Edison taught me that

So a lesson here folks. If it is nit broken, do NOT fix it. Looks like I have to trawl the Internet auction sites and find another Huawei e1550 3G modem stick because I think that is about the only thing that works with this router. My old Huawei e1550 is not broken…but it is old. I just want to be prepared. So looks like I have to get a spare, and that right soon.

Lesson well and truly learnt.

TP-LINK TL-WR740N wireless router

06/07/2013 Leave a comment

I bought this router the other day for a customer that wanted to set up a new office. She was looking for an inexpensive solution for the office, linking up a couple of computers, a printer and an NAS storage device. So I bought this one. It was a lot cheaper than the other offerings from Cisco, Aztech, Prolink and the rest. It does all the things needed to have Internet access without costing half the earth. One thing I like about it is that you can use the Gargoyle operating system in it. This thing has four 10/100Mbps LAN ports and for wireless, only one antenna. Features-wise, according to their website:

  • 150Mbps wireless data rates ideal for video streaming, online gaming and internet calling
  • Wireless security encryption easily at a push of QSS button
  • IP based bandwidth control allows administrators to determine how much bandwidth is allotted to each PC
  • WDS wireless bridge provides seamless bridging to expand your wireless network

Not too bad. Wireless on the cheap. And good quality too!

D-Link DIR-505 mini router

23/02/2013 Leave a comment

I came across this mini router last night. I was pretty impressed. It packs a router, access point, wireless repeater, and network storage drive in a device that fits in the palm of your hand. You can connect a USB storage device to this to create a shared storage space, making it easy to share files between computers and devices connected to the network. The only limitation I see is that the maximum recommended external harddisk capacity is up to 250GB. Interesting!

TP-LINK TL-WR702N nano router

20/02/2013 1 comment

The TL-WR702N is an ultra-compact router that’s similar to the TP-Link MR3020 3G router but it does not have a USB port for the attachment of a 3G/4G dongle. Its features are:

  • 150Mbps wireless data rates ideal for video streaming, online gaming and internet calling
  • Tiny – Ideal for home and travel use
  • Supports AP (default), Client, Router, Repeater and Bridge modes
  • Powered through a micro USB port by an external power adapter or USB connection to a computer

Its compact size makes it perfect for travelling, and you can even power it from a spare USB port on your computer or laptop. It utilises very little power, so you’re unlikely to drain your laptop’s battery.

Interesting this is. I had a friend who called me up just the other day to ask if there was a solution to her travel woes. Looks like the solution is right here!

Linksys WRT54G router

16/02/2013 2 comments

I have had this Linksys router for some time now. At one time, I had two homes. One was my mother’s place and one was my own home. My own home had a Linksys WRT54GC router, which performed admirably, from December 2007 till this day. This Linksys WRT54G router was at my mother’s place, replacing an old SMC wireless router that bit the dust after giving me many years of service. That SMC wireless router was one of the best I ever had and it was a shame that it bit the dust. I wanted to get a replacement SMC router but the newer ones did not appeal to me at all so I got this Linksys WRT54G router and I still use it to this day. Great router at a great price, except for the fact hat I have to reboot it every now and again. It has nothing to do with the router in case that is what you are thinking. It has to do with my telco StarHub which has one of the shittiest connections in Singapore. But then again, as I said, this is Singapore and all our telcos are shit. But I digress. get this router and you will never need to buy another router again. Linksys build great products. They may be owned by Cisco now but I still think these routers are great. They even provide you with a 4-port switch at the rear of this router!

********** EDITOR’S NOTE 19th May 2013 **********

I just upgraded the firmware of the router today. Its sad. The router kept hanging and needed a reboot frequently. It has something to do with my internet provider Starhub. They keep changing their WAN address and it causes havoc with the router. So I thought, just to make sure it is not my router that is causing the issues, I decided to upgrade the firmware. The last firmware provided by Cisco Linksys was one from 2009 so I am using tat. So far, so good, I will have to see how it goes with this. Hopefully, it should get rid of all the bugs causing it to hang
