Automatic connect to Internet when modem is ON

Automatic connect to Internet when modem is ON

Many time I received call from Technicians, Engineers from various organization that Sir my customer couldn’t see video feed in their laptop, Sir I have BSNL Broadband how to enable auto connect when Modem switch is on. If you are using BSNL broadband in India and most of the time you will be connecting to internet using a username and password. You might be wondering why you can’t connect to internet when modem switched on.
It can be easily done with few steps.
All you need to do is to setup your DSL mode to work in PPPoE mode. In this mode once the DSL link is steady the modem remembers the username and password and auto connects to internet when switched on.
If you are using a username and password to connect to internet with DSL modem (like Huawei) then that means you are most likely to be using Bridged mode. All you need to do is change this bridged mode to PPPoE mode in your modem control panel. This should work pretty much for modems supplied by BSNL or other third party modems.
Here are the easy steps….

Open your browser and point your browser to http://192.168.1.1/ to open your ADSL modem control panel. Type admin and password admin (in most cases).
If that doesn’t give you modem access page,

Next is to set up IP address and DNS IPs. There are 2 ways of doing it.
(a) First you can go to router and enable DHCP and it will automatically assign IPs to PCs you connect. You have to also enter DNS server IPs of your ISP in the router.
and the other method is assigning static IP.
(b) Go to > Network properties > Internet Protocol (TCP/IP) > enter ip, subnet mask and gateway as shown below…
(i) Set the IP address of PC in range between 192.168.1.10 to 254 (any one IP) with subnet mask of 255.255.255.0 with the gateway address of 192.168.1.1 (modem as gateway to access internet)
(ii) Next set DNS IP address to BSNL DNS IP address or if you don’t know BSNL DNS server IPs you can use open dns, dns servers lPs of 208.67.222.222 and 208.67.220.220 as an alternative to access internet.
Note: some modems use http://192.168.168.1/ for accessing control panel. Refer to your modem manual. 

Once you get into Modem Control Panel, you will need to edit WAN settings of PVC0 with VPI=>0 and VCI=>35 for BSNL connection. Edit it and set to PPPOE mode. There enter your BSNL username and password. Just edit this and leave the other PVC connections.

Here I am using Huawei modem control panel, supplied by BSNL.
Change the default admin password for security reasons.
Setup Wi-Fi security using WPA for your wireless router.

Important: Don’t leave your wireless router open. If you leave it open anybody walking by with a wireless laptop can have access to your internet connect without a password as soon as your modem is on. To prevent that secure your wireless router with a passphrase.
(i). Go to wireless setup > change SSID > home-Wi-Fi
(ii). Go to wireless security > select WPA > PSK string > Your password
Use WPA is it is better in security than WEP encryption.
Save All and Restart the modem and PC.
·  To check connectivity try pinging both to router and websites. Go windows start > run > command
ping 192.168.1.1
ping yahoo.com
Once you switch ON the modem and the DSL link becomes stable, you should be able to access the internet. No need for username and password.

Plus if you own a nokia phone or ipod that supports wifi then those devices can only access internet though PPPoE mode (always on modem)

If you have messed up the settings or unable to internet, just reset the mode by restoring the default settings either through modem control panel or a reset hole at the back side of mode. Once you reset the settings, your modem will be back to bridged mode and you will be able to connect to internet using traditional way of broadband username and password.

Smartphone innovation will increase with 5G

Smartphone innovation will increase with 5G

Innovation in cellular and other supporting technologies as well as in applications will sustain the rate of smartphone improvements.
Press and industry analyst response to the recent announcement of the iPhone 7 has been lukewarm. For example, The Economist notes the “main novelty” is it no longer has a conventional jack for headphones. That newspaper reckons “after almost 10 heady years, dating from the release of the first iPhone in mid-2007, both growth and pace of innovation have slowed markedly in recent months.” I doubt the pace of innovation is really slowing or that this could ever be reliably determined over months rather than years. However, in conclusion, The Economist also wisely rejects “talk of an end to the smartphone era.”
Improvements under the hood
Whereas some smartphone innovations are very overt and revolutionary; others are not so apparent to consumers and are more evolutionary, but are at least as significant. The multitouch capabilities included in the first iPhone were literally very tangible and enabled access to regular web pages, as opposed to the repurposed content hitherto required for small displays with WAP browsers. The iPhone transformed browsing on a small device connected to the internet via Wi-Fi, but remained hobbled as a truly mobile device – six years after the introduction of the first 3G networks – with only 2G cellular connectivity and a maximum downlink speed of only around 150 kilobits per second achievable. Uplink speeds were much slower still.
Performance has improved enormously over the last nine years. LTE data rates are 1,000-times faster – at hundreds of megabits per second in the downlink, tens of megabits per second in the uplink, and latencies have reduced from several hundred milliseconds to tens of milliseconds. Ever-higher maximum cellular data rates achievable in the uplink and the downlink on the succession of iPhone models illustrates the gradual yet relentless improvements in cellular technology. For consistency over many years, the following chart includes fastest downlink data rates in device testing on commercial networks or considered likely following announcement of each new iPhone model, as indicated in contemporaneous analyst and press reports. Maximum speeds depend on latest technologies in devices and in network upgrades, which can take a year or so to roll out. Actual speeds are also affected by a user’s location and radio interference with other users nearby. For example, AT&T Mobility’s customers in New York and San Francisco suffered with slow speeds and poor availability following the introduction of the iPhone 3GS in 2009. Such problems are rarely so severe these days.

Exponential growth in downlink speedsOther fundamental device improvements include the number of cellular standards and frequency bands supported. The first iPhone was a single-mode GSM/GPRS/EDGE device. Over the years, CDMA, TD-SCDMA, LTE-FDD and LTE-TDD have been added to make iPhones multimode devices. Multiple frequency bands are also employed with each standard. In particular, large and increasing numbers of bands are required for LTE. Since the introduction of the iPhone 5 in 2012, with support for LTE in up to five bands, the number of LTE bands supported has increased to 23 bands in the iPhone 7. Squeezing more and more modes, bands and other cellular functions into smartphones and getting higher and higher levels of radio performance out of them is no mean feat. It requires major innovative efforts and accomplishments in various ways.

A lot of inspiration and perspiration
Cellular technology developments have included some relatively large step-changes, for example, with new air interfaces; but developments mainly arise in a series of many incremental improvements. Even generational upgrades can take years to deploy across networks before benefits can be fully enjoyed. Until at least the turn of the millennium, cellular technology improvements were overwhelmingly in supporting voice and the most basic data capability imaginable with a maximum of 140 characters per text message. Since then, innovations have been focused on exponentially increasing speeds and network capacity for data. Numerous new technologies have been developed and introduced in the last decade. Terminology for these includes dual carrier, carrier aggregation, inter cell interference coordination, coordinated multipoint and heterogeneous networks among many others which have collectively boosted spectral efficiency, increased end-user data rates, increased network capacity and lowered latency.

The development of these standard-essential technologies is a massive coordinated endeavor involving numerous companies. According to analysis by Signals Research Group on 262,773 submissions to five 3GPP working groups from 1999 through December 2014, 43,917 documents were approved for inclusion in standards. The approved documents include 3G only, LTE only, and 3G and LTE documents as well as submissions that fall outside all of these three categories – documents pertaining to GSM/GERAN or IP multimedia subsystems are examples. More than an estimated 1 million man-hours is spent actually in 3GPP working group meetings each year. However, working group activity is merely the tip of the iceberg. Mobile communications sector research and development investment is estimated at up to $100 billion per year. Much of that is in development of standard-essential technologies including 4G recently, and now also in 5G.
‘You ain’t seen nothing yet!’

Each successive new generation of cellular technology has been driven by increasing technology developments, innovation and adoption by wireless carriers and consumers. Following the rather disappointing data rates and lackluster adoption of 3G W-CDMA between 2001 and 2005, the pace of all the above increased with the introduction of HSDPA from around 2006, and then increased again with the introduction of LTE from around 2010. Industry enthusiasm for 5G is also great and so we should expect the rate of innovation to be maintained, not diminish, with the expected introduction of 5G toward the end of the decade.


Whereas demand for 5G will be dependent on new applications such as those in artificial intelligence and augmented reality, some of those applications will only be possible by the improved performance such as ultra-low latency and ultra-high availability, as well as higher data rates that 5G communications promises. Many innovations and improvements will be required for new types of devices and services such as with the “internet of things,” but smartphones will also be in the frontline.
