replace network card in toshiba laptop?

[akeim1]

I have a toshiba laptop satellite C855D-S5351 and the wi-fi only sees 2.4 wifi networks. Can I upgrade the nic card in it to see 5 wi-fi networks?

Go to Amazon/eBay/etc, and search for "Satellite S53551 WiFi card". Check whether any of the results includes 5GHz band.

You might have troubles with replacing if your Toshiba has one antennae only. so you better check what you have inside.

Your other (esier) way is to get USB WiFi adapter.
