Setting up Linksys WiFi router with Airtel Broadband June 4, 2008

Posted by xk0der in : Miscellaneous , 16comments

I bought a Linksys WiFi router last weekend. I had a little bit of trouble configuring it, although the problem was trivial, it took me some time to figure it out. I’m jotting down some notes here about what I did to resolve the problem. ( I’ve have some tips at the end of this post which you may find usefull for use with linksys (and probably other) routers and with most DSL modems.)

The Problem
The beetel DSL modem installed by Airtel has the IP address set to 192.168.1.1. The Linksys router (and probably other routers as well) use the same IP address (192.168.1.1) as their default IP address for accessing their configuration page. This causes an IP address conflict and hence the router wouldn’t be able to forward IP packets to the modem.

The Solution
1) Insert the installation CD/DVD provided with the wifi router and follow the instruction for installing the router. During the installation (Probably at the final step) the router will fail to detect Internet connectivity. That’s fine, as this is the problem we are resolving. Leave the setup window open and proceed to next step.
2) Open your favourite web-browser and enter the following address in the URL bar : 192.168.1.1
3) The above step should open the Linksys configuration page. If you are prompted for a username and password, enter admin for both the fields. If you had set a router password in step 1 enter username as admin and the password you had set in step 1. Before the username and password is asked you might be displayed a page with 3~4 icons, labeled WAN, LAN etc. select the WAN Icon, enter the username and password as described above, if prompted for.
4) On the page displayed select Setup tab (most likely the first tab) and under that select Basic setup (The exact name/text might vary but would most probably be something similar). Scroll down and locate the field Local IP address. The default value for this field would be 192.168.1.1, change it to 192.168.0.1.
5) Scroll further down the page and click on Save Settings. Reset your router and DSL modem (Power them OFF, wait for 10~15 seconds and power back ON). Wait for around 1~2 minutes (So that the Router and DSL modem have properly rebooted).
6) Complete Installation of the router (Click ‘Try Again/Re-try’ in the setup window we left open in step 1)

You should now be able to browser Internet properly on the wired (directly connected) computer. Setup your Laptop and Desktops with WiFi Ethernet card/adaptors to connect to the WiFi router. After that you should be able to access Internet through them.

Tips

  • Always setup a WPA/WEP key (pass-phrase) for your WiFi router for thwarting unauthorized WiFi piggybacking.
  • For most users WPA Personal (with default settings) should work good enough. You can set/change the pass-key for WPA Personal by logging to the web-based router configuration pages. Select Wireless tab in the configuration page and under that select Wireless security. Select WPA Personal for security Mode field and Change the field labeled WPA Shared Key. This is the key you will enter when connecting to your WiFi router form you laptop or other computers with Wireless Ethernet cards.
  • Do not buy the WiFi router provided by Airtel :) , it is expensive (around Rs.500~Rs.1000 more than other similar quality routers) and from their own company Beetel (Yup, Beetel is owned by Bharati group). And I haven’t heard/read good reviews about Beetel WiFi routers.
  • Remember: to access the Router configuration pages you need to enter the IP address you entered in step 4 (192.168.0.1), the address 192.168.1.1 will take you to DSL modem’s configuration page.
  • Default username and password for DSL modem is admin and password respectively.
  • You may remove the directly connected computer after your WiFi router is setup properly. You need a directly connected computer for fist time installation and configuration of the WiFi router.

I hope this post was of some help to all the Bharti-Airtel broadband users. Thanks for reading. :)

Problems with Yahoo Mail June 3, 2008

Posted by xk0der in : Miscellaneous , 2comments

For the past 3~4 days I’ve been experiencing problems with Yahoo! Mail. I’ve asked few of my friends and relatives and they all seem to be having the same problems. The problem is affecting both Yahoo Mail classic and the new ajaxian Yahoo mail.

Symptoms observed
1) Yahoo! Mail rejects your login credential straight away. You are not able to login, either using just your yahoo ID or the (recently added mechanism) your full yahoo mail address (yourid@yahoo.com).
2) You are able to login, but the page is not rendered properly. Yahoo mail classic displays your mails but clicking on them wouldn’t open them (only mail subject is show, the body is missing). New Yahoo Mail would render only partially, contents of folders (Inbox etc.) are not listed.

I’ve tested the problem on Linux (Fedora, Ubuntu) and Windows XP with variety of browsers. Here’s the complete list of browsers

Windows XP: IE7, Opera, Firefox 2
Linux (Ubuntu): Opera 9.27, Firefox 2, Firefox 3 beta, Epiphany
Linux (Fedora): Opera, Firefox 2, Firefox 3

On Epiphany, Yahoo Mail tends to behave properly most of the times, but on all other browsers it mis-behaves 100% of times. (This is my observation).

I dunno what the guys at Yahoo are doing but this is really p*ss*ng off their users. I am, for sure, really irritated. I use Yahoo Mail heavily and this is causing real inconvenience to me. It is not just a few minutes glitch, its been consistently happening for a long time now. Are there any other people experiencing the same?

Update: 4th June 2008
It seems Yahoo is finally aware of the problem(2) http://www.ymailblog.com/blog/2008/06/external-accounts/

Quoting from the Yahoo Mail Blog

We are still evaluating the reports of inconsistent html rendering, but I do have an update regarding reported issues with the retrieving of POP email from external accounts.

Our engineers have reviewed the issue, identified the root cause, and are already underway rolling out the fix. Some users should see improved performance immediately, while others may not notice it for a few days (as it hits each farm).

We are very sorry for any frustration you guys have experienced, and for not getting updates out to you sooner.

As for the problem (1) I guess it has been resolved. At least I haven’t faced any problems today logging into Yahoo mail.

Update: 10th June 2008
I guess the problems described in this post have been resolved by Yahoo, I haven’t had any problems for more than 24 hours now. A big thanks to Yahoo! team. Hopefully things wouldn’t break down again, and if they do, would be resolved quickly.

Apache 2 on Fedora Core 4 May 11, 2007

Posted by xk0der in : Miscellaneous , add a comment

Recently while installing Apache 2 web server on a Fedora Core 4 machine, I ran into some very peculiar problems.

Apache would compile cleanly, install perfectly but when I would start the web server it would fail complaing about, failed to load shared library (some ldap and others).

After much hunting and googling, i found that it’s this SELinux (Security Enhance Linux) stuff that’s creating problems.

If you too have faced a similar problem, just switch off SELinux by modifying the file /etc/selinux/config (file path might be specific to FC4), and changing the line SELINUX=encforcing to SELINUX=disabled

I happen to read this very interesting article by Tim Daneliuk

http://www.tundraware.com/Technology/How-To-Pick-A-Programming-Language/
I really don’t know if it will help anybody pick out the language of their choice, but the article makes a very good reading, specially if you like nerd humour.

what the heck is this xk0der ? well I got this name when I started a programming club named Xtreme K0ding, I found it kind of funky and hence have been using it at quite some places now! Well about this blog: Since many now have started a blog of their own, I said to myself let’s start my very own Web Log, hence this space. Anyway, I *hope* to put up some usefull stuff in here but notice the stress on the word ‘hope’ ;) That would be all in my inagural post
