I have been endeavouring to set up a CPE with the incoming internet being via a Vodafone WIFI pocket modem.

I HAVE A TP LINK CPE MODEL TL-WA5210G which works on 802.11G but seems not to want to retransmit from the Vodafone Wifi modem.

All other devices connect where they are 802.11bgn compatable.
I have a TP Link range extender that readily retransmits from the Vodafone Wifi modem but TL-WA5210G has got me stumped.

Any guidelines would be appreciated.
