These is an old 3 year old store. My Westell 6100F just quit working on the net. The internet light would just light red. The Verizon tech in India advise to get a replacement unit, but I didn't. Co-worker had an unused Westell 327W unit setting as a dust collector. Fast forward to now, I like to buy a new modem-router from Verizon, but the web page is blank. Well I mean there are no modem-router available to me. Could someone please explain and advise me on other option?
Any modem that can handle ADSL will work. There are literally hundreds of them available on eBay. Westell 6100s are selling from $5-$40. As noted above, you can buy a Westell 7500 for a little more, or you could step up to a Westell 327W, which also includes a router and wi-fi.
Of course, there are other brands. Verizon also uses Actiontec - the GT701 is probably the most equivalent to your Westell, and they also sell a router/wi-fi modem, the GT704WG. Both of these can be had for less than $50 on eBay.
