UPDATE AGAIN:
The signal strength keeps yo-yoing up and down between 20% and 80% +-5 or so.
In the logs I noticed that the following all happens within a single second (but this scenerio is repeated many times over an hour)
And, ten seconds later and disconnects again.Code:04/05/12 07:49:18 AM jerry-Aspire-7739 kernel [ 4416.560389] wlan0: associated 04/05/12 07:49:18 AM jerry-Aspire-7739 NetworkManager[1115] <info> (wlan0): supplicant interface state: authenticating -> associated 04/05/12 07:49:18 AM jerry-Aspire-7739 NetworkManager[1115] <info> (wlan0): supplicant interface state: associated -> 4-way handshake 04/05/12 07:49:18 AM jerry-Aspire-7739 wpa_supplicant[1163] WPA: Key negotiation completed with d8:5d:4c:b9:f4:ba [PTK=CCMP GTK=CCMP] 04/05/12 07:49:18 AM jerry-Aspire-7739 wpa_supplicant[1163] CTRL-EVENT-CONNECTED - Connection to d8:5d:4c:b9:f4:ba completed (reauth) [id=0 id_str=] 04/05/12 07:49:18 AM jerry-Aspire-7739 NetworkManager[1115] <info> (wlan0): supplicant interface state: 4-way handshake -> completed 04/05/12 07:49:18 AM jerry-Aspire-7739 NetworkManager[1115] <info> Activation (wlan0/wireless) Stage 2 of 5 (Device Configure) successful.

I went searching for solutions again and found this, posted on MARCH 30, 2012:

I found a similar posting that said the "receive performance" in rtl8192ce was fixed in the 3.2.0-14 kernel.3.0-stable review patch. If anyone has any objections, please let me know.Date Fri, 30 Mar 2012 12:57:54 -0700 From Greg KH <> Subject [ 032/108] rtlwifi: rtl8192ce: Fix loss of receive performance
------------------
From: Jingjun Wu <jingjun_wu@realsil.com.cn>
commit a9b89e2567c743483e6354f64d7a7e3a8c101e9e upstream.
Driver rtl8192ce when used with the RTL8188CE device would start at about
20 Mbps on a 54 Mbps connection, but quickly drop to 1 Mbps. One of the
symptoms is that the AP would need to retransmit each packet 4 of 5 times
before the driver would acknowledge it. Recovery is possible only by
unloading and reloading the driver. This problem was reported at
https://bugzilla.redhat.com/show_bug.cgi?id=770207.
The problem is due to a missing update of the gain setting.

I never had any problems with my RealTek wireless chip running -14 through -17, but the problems appeared in -18 and all since then, so a regression has been introduced.
This patch in this annnoucement is for the 3.0-stable kernel.

UPDATE about Chromium...
I had been lucky with Chromium starting up every time I clicked its icon in the application-launcher. I usually open it up and leave it open, since I spend most of my time using the browser.
Well. I closed it this morning and then opened it up. It wouldn't open.
It turns out that when Chromium closes it does NOT remove all of its threads from the system processes. Restarting Chromium fails if there are still Chromium threads in the processes.
If I kill them then Chromium starts like it is supposed to."A nation that is afraid to let its people judge the truth and falsehood in an open market is a nation that is afraid of its people.”

ANOTHER UPDATE:
April 6th, 7th and 8th were the worse days yet for Precise on this Acer 7739.
I had upgraded to the "-21" kernel but that didn't help. I didn't want to downgrade to the "-18" or earlier kernel. No params settings would make the rtl8192ce driver work reliably on this laptop. My wireless was down so often that I had to resort to my ethernet cable to establish a reliable connection. I couldn't trust the wireless connection for updates or other downloads that might fix the problems.
After updates on Saturday things got worse. On two occasions my display blacked out. On one occasion the laptop powered off in a snap and without warning. Checking the system logs revealed thousands of msgs about "Intel ips", and "MCP" and other stuff I reported on March 26th. Some suggested that "intel_ips" be blacklisted. I did that and my avg running temperature rose 10F and the wireless was unusable, so I removed it. But, this laptop was running significantly hotter than it had been in the past, and it seemed to become unstable at 140F, even though the CPU is rated to 190F. Yesterday I seriously considered buying a fan for it.
I spent most of Sunday afternoon and evening researching the problems. It seems that the "Intel ips" power problems first appeared in 2007 and were fixed, but a regression has snuck back in. All in all, my problems had the appearance of being caused by the kernel. Despairing, I went to the repository in the hope that the "-22" kernel would be there and that it would solve my problems. Last night, about 12:30AM, I discovered that it was there. I installed it and rebooted. I played minecraft for an hour to test it out and then went to bed.
This morning at 9AM I fired up this Acer to give the new 3.2.0-22 kernel a shakedown. My rtl8192ce connected using 11n at 150Mb/s and has remained connected every since. The MCP and " intel ips 0000:00:1f.6: MCP power or thermal limit exceeded" messages have ceased. The rtl8102ce power off settings are stable and it doesn't jump back and forth between 12Mb/s, 15Mb/s and 150Mb/s randomly or under load. More important, it doesn't show a 15Mb/s connection speed but time out on any webpage. My average unadjusted temp setting while using Chromium has been 100-102F, which is what it averaged before the troubles began.
Now I am going to run the graphic intensive apps and see how they play.

UPDATE AGAIN:
I have been using this Acer 7739 with the 3.2.0-22 kernel and the latest updates for over 12 hours.
The rtl8192ce wifi driver stayed up at 150Mb/s for those 12 hours and the system log shows only three drop outs. The first was 1/2 hour after I started, the second was an hour afterwards, and the third was at 5:45pm.. Chromium has been up the entire 12 hours and I never noticed a single time out or page hang, so the dropouts were quickly restored. Chromium started immediately upon its first summons, and I closed and restarted it several times but it never failed to quickly start.
There are hundreds of the following message:
but they didn't appear to affect performance. The temperature never went of 150F (That I noticed), and when Minecraft is closed it drops to the average temp of 107 F, when Chromium is open.04/09/12 09:36:27 PM jerry-Aspire-7739 kernel [43238.402943] intel ips 0000:00:1f.6: MCP limit exceeded: Avg power 39946, limit 3500004/09/12 09:37:07 PM jerry-Aspire-7739 kernel [43278.340382] intel ips 0000:00:1f.6: MCP limit exceeded: Avg power 35807, limit 35000

All in all, if these 12 hours are any indication, Precise is back to the stable platform it has been for me from Jan 3rd to about three weeks ago."A nation that is afraid to let its people judge the truth and falsehood in an open market is a nation that is afraid of its people.”

UPDATE: Yesterday marked the second 12 hour day without any of the previous problems.
The rtl8192ce problem is much improved but there is still one nagging issue, occasionally SLOOOW internet speed. My connection speed remains firm at 150Mb/s (no yo-yo-ng) but it becomes laggy.
When this happens I run
ping goggle.com
to see if my connection is still up because the network-manager is notorious for not having a connection yet showing a connection.
Looks normal, right? That's part of the problem. In this run the time between lines was less than a second. When the connection slows down, the google ping shows exactly the same output,, except for an occasional time=127ms, but more importantly, the actual time between pings is five seconds, not a fraction of a second! The icmp_req is sequential and without missing packets, and the times are still in the 55 ms time range, give or take a couple ms, but other than that you'd thing I had a normal connection. It really gets aggravating when watching videos because the 5 second pauses seem to pile up .... there would be a brief 5 seconds of play followed by a minute or more of spinning wheels ... rinse and repeat. Once the local cache is filled the video plays all the way through at normal speed.jerry@jerry-Aspire-7739:~$ ping google.com

So, there is still some kind of problem with the rtl8192ce wireless driver, but it is much better than it was previous to moving to the -22 kernel."A nation that is afraid to let its people judge the truth and falsehood in an open market is a nation that is afraid of its people.”

Not necessarily so. Try switching to a different server (Download from: in Software Sources). I was having such issues, even on my wired connection at the house. I called several times to my ISP Internet Help Desk to complain, asking if they 'throttled' throughput at times (other, much larger, less honest ISPs do this). They said 'no', and I do believe them. They monitored my connection and ran a few tests and noticed there were large latency delays at certain legs of the source to destination (my PC) route. They noted that the 'source location' was in Europe (Canonical) -- I was doing routine, normal daily updates. They suggested trying a different server, so i did. Made a huge difference. So now, when I don't get the throughput that I expect, and that I am paying for, I try a different server, and that usually resolves it.Originally posted by GreyGeek View PostWindows no longer obstructs my view.

Different server?Originally posted by Snowhog View Post
I don't know of another way to get to google.com unless I use an onion router, and that certainly isn't going to boost my speed.
YouTube videos lag, as I indicated, using wireless, but are as fast as my connection allows using a cable.
When I switch to cable there is no delay on any site I visit. With my wireless connection it doesn't matter what site I visit, the slow periods come and go, intermittently.
My ISP is Earthlink.net, which rides on RoadRunner's cable. Every connection I make has to go through one of their servers."A nation that is afraid to let its people judge the truth and falsehood in an open market is a nation that is afraid of its people.”
