BSNL sells a wireless router (Type-IV) for 2000/- only, to their customers.
I recently purchased this to replace my old Type-I router. It's a Huawei
Sterlite SmartAX MT841 with 1 WiFi (comes with a PCMCIA slot in modem, and
an addon PCMCIA WiFi accessory card), 4 ethernet and 1 USB port. It has the
usual ADSL modem capability, that most of the Netgear/Linksys routers lack.
Performance is good enough for its price, and WiFi signals are decent too. See
if you can buy it directly from them, otherwise you can coerce a friend with
a DataOne connection to file a request application form with 2000/- in cash
to their office and get you a shiny new wireless boradband modem/router.
NOTE: Don't forget to ask for the PCMCIA card, which is included in the price.
I know a few who weren't provided with the free accessory card, or were asked
to pay 600/- for it. If you don't get one, you can still buy an aftermarket Linksys
card and use it for WiFi.
