Windows 7看不到我的5 GHz路由器模式，只看到2.4 GHz模式 [英] Windows 7 doesn't see my 5 GHz router mode, sees only the 2.4 GHz mode

问题描述

早上好！

1. 背景.我最近购买了一台装有Windows 7， 64位，Premium Home Edition的东芝A505-S6017"笔记本电脑:(1)我有一个 32位，PC节点的>功能齐全的家庭网络. (2)我的路由器是"Netgear Rangemax双频Wireless-N路由器WNDR3300". (3)我的新笔记本电脑有一个内部"Realtek RTL819无线局域网，302.11nb/g/n(草稿)PCE-E NIC"，(4)我的笔记本电脑收发器是"Microsoft 2.4GHz，V1.0"(5)已在路由器上设置了两个无线网络，一个用于2.4，另一个用于5Ghz，并且可以根据需要在这两个之间进行切换.

2. 问题. Windows 7找到了2.4GHz，没有汗水，但看不到5GHz.我想使用5GHz，因为担心我的2.4会干扰家用无绳电话，微波等也使用2.4的无线电话，此外，5GHz是速度/现代化优势的首选.

3. 迄今为止的操作.我已经以多种方式遵循Windows 7进行家庭网络搜索和设置过程的过程.我研究了(全部/大部分?)涉及OEM的文档，论坛和Internet范围内的Google查询.我找不到该问题的解决方案或建议.

我迫切需要一个解决方案，因为我需要从笔记本电脑设置对其他计算机的访问权限.我正在考虑将较旧的PC升级到Windows 7，但首先需要解决此问题.您可以帮助分析和解决此问题吗?

非常感谢您可以给予我的任何考虑，

Good morning!

1. Background. I recently purchased a "Toshiba A505-S6017" laptop with Windows 7, 64-bit, Premium Home edition installed: (1) I have a fully functioning home network with 4 (other) XP, 32-bit, PC nodes. (2) My router is a "Netgear Rangemax Dual Band Wireless-N Router WNDR3300." (3) My new laptop has an internal "Realtek RTL819 Wireless LAN, 302.11n b/g/n(draft) PCE-E NIC," (4) My laptop tranceiver is "Microsoft 2.4GHz, V1.0" (5) I have set up two wireless networks on the router, one for the 2.4, the other for the 5Ghz and can switch between the two, as desired.

2. Problem. Windows 7 found the 2.4GHz, no sweat, but does not see the 5GHz. I want 5GHz access since am worried about my 2.4 interfereing with household cordless phones, microwave, etc. which also use 2.4 -- plus, 5GHz is preferred for the speed/modernization advantages.

3. Actions to date. I have followed Windows 7 procedures for home network search and setup processes in many ways. I have researched (all/most?) involved OEMs'' documentation, forums, and Internet-wide Google queries. I can find no solution or suggestions for the problem.

I am desperate to find a solution, as I need to set up access to my other computers from my laptop. I am considering upgrading my older PC''s to Windows 7, but first need to address this issue. Can you help analyze and solve this?

Thanks so much for any consideration you can give me,

David N.

推荐答案

我的猜测是您的笔记本电脑NIC与5Ghz频段不兼容.

顺便说一句，您没有提供NIC的完整型号.

My guess is that you laptop NIC isn''t compatible with the 5Ghz band.

BTW, you didn''t provide the entire model number of the NIC.

东芝使用的Realtek RTL819系列芯片是;

RTL8191SE是仅适用于2.4GHz频段的单芯片802.11a \ b \ n解决方案
适用于2.4GHz频段的RTL8192E + RTL8256
适用于2.4GHz和5GHz频段的RTL8192E + RTL8258

因此，取决于您拥有哪一个，您将确定是否可以使用5GHz频段.

The Realtek RTL819 series chips used in the Toshiba are;

RTL8191SE which is a single chip 802.11a\b\n solution for 2.4GHz band only
RTL8192E + RTL8256 for 2.4GHz band
RTL8192E + RTL8258 for 2.4GHz and 5GHz bands

So depending on which one you have will determine if you can use the 5GHz band at all.

Realtek已通过电子邮件通知我，东芝笔记本电脑随附的无线网卡无法识别5 GHz频段.只能使用2.4 GHz频段.

Realtek has notified me via email that this wireless card supplied with toshiba laptops will not recognize the 5 Ghz band only the 2.4 Ghz band.
