I have added the 7 dbi eBay external antennas to an E2000 - and installed DD-WRT build 15962 in it. When I look at the db signal strength coming out of it (using inSSIDer) I see the signal strength fluctuating in a repeating pattern (the green line in attached image). I do not see the fluctuation with a Linksys wrt160n V2 running stock firmware (the red line in attached photo). I had expected to see the E2000 db level to be much higher than the wrt160n due to the external antennas. I have the E2000 at the default 71 mW TX power.
Note: I was connected to the wrt160N when running this test - and it seems (see subsequent posts) the level db line will appear for whatever AP the computer running inSSIDer is running. So it does not appear to be a problem with the external antennas.
Fluctuating db level

I also tested my E2000 with the internal and then with external antennas. My results were exactly like yours with the repeating pattern db fluctuation with external antennas when tested with inSSIDer. I'm running DD-WRT DD-WRT v24-sp2 (08/12/10) std-usb-ftp (SVN revision 14929).
I guess a stable flat signal is better than the jumpy signal so I pulled the external antennas.
I tried connecting to one AP - then the other - and notice that the fluctuations seem to be on whatever AP I was not connected to.
I did a further test with a second laptop connected to one of the AP's and my laptop running inSSIDer connected to the other but the signals stayed the same - meaning the signal from the AP my inSSIDer was not connected to would fluctuate while the AP I was connected to would stay level.

I re-connected the external antennas to the E2000 and ran inSSIDer on an Acer laptop. That laptop let me disconnect from the routers and still keep inSSIDer running (something I could not do with my Lenovo X201i laptop).
Note on this chart - from running inSSIDer on the Acer - how both routers db's are fluctuating when the laptop is disconnected from them - then when I connect to the E2000 (green line) the db levels out until I connect to the wrt160N (red line).

Well, my 1st Router Mod is complete, I 1st added a small fan dead top center of my Cisco E2000 and added 1/2" thick rubber feet on bottum for air flow, and put a ramsink on the exposed broadcom chip that I noted ran hot, then I replaced the power supply that had a 1000 mA Rateing to one slightly larger, 1250 mA rateing to ensure that the router would have plenty of power with extra fan and so forth. Then I ordered these 7dbi external antenna from http://www.ebay.com/itm/7dBi-Antenna-Mod-Kit-Linksys-E2000-No-soldering. I ONLY use the 5Ghz side so these 2 where enough. I hooked one of the externals to the 5 Ghz tx/rx plug then the other external Antenna to the rx only plug. I left the 2.4 Ghz internal antenna hooked up.
Results: Unit runs much much cooler and I gained right around 7db with a very straight/stable signal on my 5Ghz band according to inSSider 2.0
oh as an update kinda..lol I played around, with 5 Ghz band it seemed the best boost was with both external antenna set straight Horizontal and for the 2.4 Ghz band, set straight vertical. and lastly I came across this cheap and easy mod for my sons pc desktop http://www.youtube.com/watch?v=48VDsqjNPss and it worked out Great!! same rules applied to this mod as the Antenna mod, 5 Ghz Horizontal mounting of usb adaptor and can an Vertical for 2.4 Ghz.
