Rainge of wireless routers
Hi I am with AOL/Talk Talk. I have a wireless router Huawei Echolife HG521 and have just purchased on line a USB wireless dongal D-Link DWA-140 not arrived yet. I tried to ask AOL help desk for the range. They are in asia and do not seem to know. One minute they say 30 feet the next minute they say 30 Meters. Can someone give a best guss for reliable and a maximum achevable please.
TIA Desmond. |

Can someone give a best guss for reliable and a maximum achevable please. The 802.11 specifications indicate range, viz. Wireless N should have an appreciably longer range than Wireless G. Local conditions (obstructions to RF frequencies between the two wireless stations) are the factors most likely to limit range in home networks. Most US manufacturers promise 30 to 100 meters range i.e. enough for most home users. 30 feet = 10 m. is ridiculously small, which implies your responders in Asia seldom need to consider max. range. -- Don Phillipson Carlsbad Springs (Ottawa, Canada) |

You get a Faraday cage effect and your signal is attenuated, so 20-30 feet is more like it if you're behind a thick concrete wall and the router is on the other side. RL |

Eventually, if you get far enough away, the thing can't stay connected any longer. The customer reviews here, for the DWA-140, span a large range of dates. That implies there could be several different "revisions" of the adapter, each with different chipsets. The different revisions might not have identical characteristics. You may not be able to use a review from 2009, to predict how the 2012 version works. http://www.newegg.com/Product/Produc...82E16833127244 With regard to your Huawei router, there aren't many reviews here, but it's not looking good so far. At least it supports N. But if the radio portion doesn't work well, the world's greatest USB dongle isn't going to help. Both ends play a part in the connection quality. http://www.amazon.co.uk/TalkTalk-wir...320425-5698005 Paul |

Hi I have read the review Paul posted at the bottom of his reply. I am having this difficulty. and the revews do not paint a pretty picture. I am confused with what two of you have said to get it working.
Taken from that last link ..... SlickRick 9/18/2010 9:42:47 PM However after reading several reviews here on Newegg, I went to the RaLink website and downloaded the RT 2870 driver How do I get that driver? AND Brianod 8/30/2010 9:05:31 PMhis came with firmware 1.50 (rev B Adapter) but Dlink says that's no good for Win 7 64. Had to go to Dlink and download 1.60 I have searched for updated drivers. I did find one claiming to do the job. DWA-140_B2_FW_v1.71s0062.zip This has drivers for Vistax64, Vistax86, Win7x64, Win7x86, WinXPX64 ans WinXPx86_Win2K. plus a standard setup.exe. I tried that and it made no diffrence. D-Link do not apear to have an email support and the phone number is 10p ber minute. Any help on this driver 1.60? Desmond. |

Sorry should have added a request to the above for a decent adaptor for
Windows 7/64 Desmond. |

I tried that and it made no diffrence. D-Link do not apear to have an email support and the phone number is 10p ber minute. Any help on this driver 1.60? Desmond. If I was doing this, the first thing I'd need to do, is verify it really is based on an RT2870. As I indicated, the DWA-140 has existed for several years, which is a long time for an adapter, and implies there are several revisions. I would want to use my utilities to tell what kind of chipset it is first. This is an example of a link for Ralinktech. If you have a USB adapter, that's the driver at the top of the list. Make sure the chip number and the interface type are correct, before downloading. http://www.ralinktech.com/en/04_supp...ort.php?sn=500 When I tried downloading, what I got was this 30,769,885 byte file. It appears to be packed "Chinese style", not a good sign. Like some of those webcam drivers I don't trust. I can't open this with 7ZIP, because they used a packer. IS_AP_STA_RT2870_D-3.2.9.0_VA-3.2.9.0_W7-3.2.9.0_RU-4.1.7.0_AU-4.1.3.0_042412_1.5.19.0WP_Free.exe This is the AV scan from a week ago. It's clean. https://www.virustotal.com/file/d78b...2aba/analysis/ I use Virustotal sometimes, for the "Additional Information" tab. This is what it shows for the download. "TrID DirectShow filter (45.2%) Windows OCX File (27.7%) Win32 Executable MS Visual C++ (generic) (8.4%) UPX compressed Win32 Executable (6.8%) --- Win32 EXE Yoda's Crypter (5.9%) --- PEiD packer identifier Armadillo v1.71" --- So it's chock full of goodness. Just for the record, a 30MB download is totally unnecessary for a Wifi device. An NDIS style driver, would probably be a fraction of that. If I check the unofficial list of USB entries, this is what is available for your adapter. So the adapters are made with more than one chipset. Because there are only unofficial lists for this sort of thing, we can't be sure the list is complete. But at least this shows, more than one chipset is used. 07d1 D-Link System 3c09 DWA-140 RangeBooster N Adapter(rev.B1) [Ralink RT2870] 3c0a DWA-140 RangeBooster N Adapter(rev.B2) [Ralink RT3072] When the installer is running, these are some of the files it uses. (I checked this in Ubuntu, using WINE.) 1168 2006-05-17 00:58 default.pal 86880 2010-12-31 10:07 devcon64.exe 83296 2010-12-31 10:04 devcon.exe 890 2011-03-14 15:20 DisplaybyHWID.ini 39 2012-04-24 17:45 FontData.ini 11311 2011-10-12 16:05 HWID.ini 102400 2011-01-20 20:44 InstAPI.dll 102832 2006-05-18 00:19 _IsRes.dll 208304 2007-04-05 14:37 isrt.dll 12288 2012-04-24 17:45 _ISUser.dll 4392 2011-03-31 10:24 License_JP.txt 3026 2011-03-31 10:22 License_SC.txt 3026 2011-03-31 10:24 License_TC.txt 6708 2011-03-31 10:40 License.txt 354870 2012-04-24 17:45 setup.inx 5632 2012-04-24 17:45 StringTable-0009-English.ips The "devcon" (that's actually a Microsoft file) can be used to list hardware in the computer, from the command line. That could be what they're using to check the USB ID of the wifi adapter. The "devcon64" is the 64 bit version, which is a bit harder to locate (not available for immediate download from Microsoft, has to be extracted from a CD sized download). Before downloading the RalinkTech installer, you can get a copy of "devcon" from here. Only the 32 bit version works. The IA64 version is not for your PC (it's for Itanium). (Maybe some other utility could do this in a more friendly way.) http://support.microsoft.com/default...;EN-US;Q311272 From the command line, you place the devcon.exe file in the current working directory, and use a command like this: devcon hwids * myhwids.txt Then, open "myhwids.txt" file with a text editor. Now, the following are all the entries listed for D-Link, in that RalinkTech download. This list is extracted from "HWID.ini". Not all of these will be your adapter, but this is to give some idea how many D-Link designs use those two chipsets. [RT2870] DeviceID_7 =USB\VID_07D1&PID_3C09 DeviceID_37=USB\VID_07D1&PID_3C11 DeviceID_44=USB\VID_07D1&PID_3C13 [RT3070] DeviceID_21=USB\VID_07D1&PID_3C0A DeviceID_27=USB\VID_07D1&PID_3C0B DeviceID_34=USB\VID_07D1&PID_3C0D DeviceID_35=USB\VID_07D1&PID_3C0E DeviceID_50=USB\VID_07D1&PID_3C0F DeviceID_52=USB\VID_07D1&PID_3C15 DeviceID_71=USB\VID_07D1&PID_3C16 DeviceID_92=USB\VID_07D1&PID_3C17 The other thing to note there, is the Wifi adapter doesn't use an RalinkTech ID number, it uses D-Link, meaning it's possible for a Wifi adapter to be "disguised". I don't like this practice. Instead, they should be using a SUBSYS number to identify the designs. The driver install, includes a Ralink WLAN Utility, which is pictured here. http://www.3dvelocity.com/reviews/as...s/image042.jpg Anyway, that's the RalinkTech driver. Have fun, Paul |
