A couple of things to consider:
First I don't know if you are in the linux world or windows world; but I use a a filesystem that has a strong checksum per block (zfs). I also use raid and zfs will repair bad data doing monthly scans (called scrubs). While bit error are not common (bad cables are the most common cause); sector remaps are not that uncommon (when a sector remap occurs the new sector will be all 0). Most disks (though seagate is extremely unfriendly); will show useful data if if you have smart enabled.
-
Off line disks will not 'remember' data forever. You didn't indicate if this is a hard disk or ssd; but either way you should probably verify the data once a year (an alternative to off line disk is a large usb stick - but likewise it will not remember data forever).
-
As to your viewing issue there are too many unknowns. First it would be helpful to know the t-put (bit rate) of your transfer both when using the disk on your system and using it via wifi. Second one needs to understand if the bottleneck is the drive, router or device. Also if this is cloud storage then the problem could be latency between you and the cloud source - i think from the description it is a hard disk on your pc. Other issues could be that the device and router are fine but the distance from your bedroom to router is sufficient to cause issue or there is a barrier (metal wall, floor, ...) hindering the wifi signal. Most phones will allow for a wifi analysis app device that will test bit rate, show packet loss and signal strength.

--
While you can upgrade your router it won't help if your wireless device does not support the faster bit rates. Also the frequency that support faster bit rates tend to have shorter range and more prone to interference.
-
There is a lot of variance in transfer rate by a mechanical drive; but 200 to 400Mb/s should be feasible.
--
802.11n or 802.11ac should get you there if your device supports it and the distance between your device and router is reasonable (couple of rooms away; same floor).
-
Naturally if your device is old it might not be able to read/process the data that fast. Last but least if your device has limited memory it might be running into memory issues which would make it very slow.
