**Note, for those having problems viewing pics, I will upload the pics to INSTRUCTABLES when I make a project for it and update the material used for the Antenna.

Ok, I have done projects like this in the past with PDAs and USB WiFi Adapters.

I find that my connection to my nearest router only gives me on average 15-25% connection.

So, I took my N810 apart and over doubled my signal, it's now at about 35-50%

First, remove the battery panel and pry off the top panel.





That little gold metal part is your antenna "connector" that contacts the mainboard WiFi PAD to the antenna strip hidden in the back.

Then pry apart the black plastic part that holds the speakers and your pathetic WiFi antenna.



Look at the green plastic coated metal strip, there is your "antenna".



Take a scribe or a sharp object and scrape away the plastic coating on each end.



Then I soldered a small strip of copper solder wick to each bare end and super glued the ends down in the corners.



Put it back together and enjoy the increased signal strength.

Future update "might" be to add an EXTERNAL connector or PIGTAIL for a removable antenna.

**UPDATE**
I have successfully modded the N810 and now my signal has jumped from an average of 60% to no less than 100% from where I usually access the router from, and I can attach an external antenna or "cantenna" for longer range.

At the moment, I am playing around with either adding a 90 degree connector OR a pigtail out the left side (I have to get a working pigtail).

I took apart the N810 just like before and removed the material I used to enhanced the antenna.
Then I drilled 5 holes to accommodate the adapter.

The middle pin on the adapter comes into contact with the "floating" pin that contacts the motherboard in the N810.

Even without the adapter pushed in or an antenna attached, my signal has increased significantly. Not sure why yet.

I went from having a quality of about 65% and a signal of -63 to -77dBm to a quality of 85-100% and a signal of -38 to -44dBm
