E1550 ------
3.6Mbps DL /
384Kbps UL
E122 -------
7.2Mbps DL /
2.0Mbps UL
That's why I have suggested E1750, E1752 and UMG181 which are all
7.2Mbps DL /
5.76Mbps UL compatible, if not interested in
21Mbps and
42Mbps cards.
Though I am, a Ritchie street regular buyer from 1969, for the past 2 Years I have kept in hold my hardware assembly / service activities. Hence not visiting Ritchie street regularly. However tomorrow, will try to visit there and let you know the available cards.
The second 21Mbps card, ( read above my review ) I bought from one individual seller from thousand light and waiting for replacement with some other brand. Afterward only, I can judge his transaction.
Regarding Kerala seller, I have replied to your PM.
