来自主题: Living版 - HUD中的tax deductibles的问题
去年买的房,现在填tax return,想确定一下那些是tax deductible
HUD中
#106: City/town taxes:
一个网站上说"Deductible as rental expense"
http://www.taxslayer.com/support/article.php?id=475
大家都是这样处理的吗?
#801(origination charge)/802/803(adjusted origination charge)
这个比较混乱,有些说801和802可以抵税,有些说803可以,还有些
说只有其中包含的point可以, 其他的origination charge不行。这个
我收到的Form 1098上没有point,但当时的确pay了point,而且在
GFE中有,应该按那个来填?(我的情况#801>#803>point, #802<0)

如果你的网速非常快以至于802.11g的速度已经称为瓶颈了,那么上dual band会有速度
上的优势,否则速度上上不多,如果你有许多蓝牙设备什么的,dual band的路由可以
让你用5gHz的频段,这样干扰比较少,dual band在速度和稳定性上应该是和单频率802
.11n 5gHz的差不多,优势是如果你有设备不兼容802.11n,dual band也可以兼容这些
设备。Dual band的路由,我知道的比如Apple Airport Extreme,Linksys E4200和
E3500都非常稳定。

另外别迷信AC,AC覆盖率还没 IEEE 802.11 abgN 的强。 150-300mbps(double
bandwidth antenna / dual band)的就够用了。
兼容性强的是abgn,可以向下兼容老设备(wireless 802.11abg)
802.11n operates on both the 2.4 GHz and the lesser-used 5 GHz
bands. Support for 5 GHz bands is optional. It operates at a maximum net
data rate from 54 Mbit/s to 600 Mbit/s.
用Wifi Analyzer 先查一下你家附近的信号状况,看看那个频段的干扰最小。通常2.
4ghz 频道干扰最多,可以使用less crowded channel (5 GHZ bands)
除非你家里都是新的设备都支持AC,那就无脑入AC。

来自主题: Apple版 - 【MBP】WIFI问题总结
我记得apple有用Intel6300,Intel6300是3x3MIMO,3个天线的。
我曾经在我的产品中也用过Intel 5100, 6200,6205,6300,甚至都到了新品试生产。
Intel的wireless card太糟糕了。特别是在802.11N下面,client之间都能互相干扰。
CPU占有率齐高。没个i7都跑不动一破无线网卡。后来不得不换成了boardcom和ralink
2x2的卡,马上cpu usage降到基本可以忽略不计,速度还更快。
我的ipad也能把我家里的802.11N的router搞死,换了好几个都没办法。这link里说的
DLink DIR系列我也试了2个,算能撑最久的了。也需要每过几天就重启router.
后来不得不找出一个802.11g/2.4GHz的旧DLink才搞定这问题。其实54Mbps也够了。比
我家里的Internet网速快。而且2.4GHz的穿墙效果比5GHz强了无数倍。

还是信号强度有问题吧?
2-3小时差太远了,就像不停的wifi搜索信号。
你试试反过来一个地点用wpa2,另一个802.1x。
就能看出来是不是tkip的问题了。

dell latitude e6410的电池,在两个地方的电池消耗速度差别很大
使用情况差不多,网络两处都是802.11g,信号都很好,至少一个是802.1x认证,一个
是wpa2/tkip加密。
但是电池坚持的时间是5-6小时 vs 2-3小时, 把power profile从balanced调成

难道这个wpa2/tkip造成wlan耗电猛增?

In general, the higher frequency, the lower penetration capability.
Therefore, if your house is really big, 2.4GHz can reach much further than
5GHz.
However, the "air quality" of 5GHz is much cleaner due to less interference
from:
1. Neighboring WiFi devices (due to lower penetration capability mentioned
above)
2. Non-WiFi household devices like microwave oven (this one is the killer,
especially for newer "efficient" models), baby monitor, cordless phone (most
of them are 2.4GHz rather than 5GHz... 阅读全帖

在 买了Acer 15.6" Blu-Ray Aspire AS5551-4200 Laptop $478.
http://www.walmart.com/catalog/product.do?product_id=14575795&f
这款电脑屏幕有些刺眼(即使将亮度调暗),外观比较粗糙,其他没发现有什么问题
。 买这款电脑主要是看它比较便宜(带Blue-Ray).是不是选用比较低廉的材料组装成
的啊?只能用比较短的时间(一年?)就不能用啊?
有必要去退掉吗?谢谢给点建议。

来自主题: Hardware版 - 请教一个无线router的问题
家里装了FIOS的wireless router,说是支持802.11n的,但我的Dell Lattitude E系列里
面还是显示无线连接书54M, 显然就是用了802.11g了.
我看了这个dell的无线网卡应该支持802.11n的.
是不是要打开什么特别的设置嘛? 多谢.

路由是e2000,用官方固件,网络模式选的wireless N only,频带auto
两台电脑的网卡一个是intel 5100,一个是5205,都支持802.11n,频带都是选的
auto
,802.11n也启用了.网络内其他设备也都支持802.11n
两台电脑挨着,路由器在大概2米外,没有障碍物,附近也没有其他无线信号
结果每台电脑的connection speed只有144Mbps,不过信号一直满格
网上邻居互传文件速度只有大概2.5MBs,网络使用率20还不到
请问下是什么原因,先谢谢了

来自主题: Hardware版 - 求推荐无线路由
直接连cable modem 有60-70 Mbps 下载速度,
连上现有的 号称 54Mbps 的linksys wireless N的 router,就只能达到 14-15 mbps,
求推荐一个能够达到60-70 Mbps带宽的无线路由,
另外是不是无线网卡也要换,现在是dw1501 wireless-n wlan half-mini
根据specs应该可以达到 72 Mbps, 但是怀疑实际达不到
Data rate (Mbps)
IEEE 802.11b: 1, 2, 5.5, 11
IEEE 802.11g: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54

还有一个问题,如果笔记本连在第一个无线路由上,那与交换机上的机器通信时速度会
受到路由器速度的影响吧(即使无线用的是802.11n,但是路由器上好像不是千兆口接
交换机)?就是这样的结构:
笔记本----无线路由——交换机——NAS,----表示无线,——表示有线
果然,刚才找到这个路由器的specs了,就是百兆口。我想干脆买一个千兆802.11n路由
好了,然后就把这个老路由器作为passthrough。大家有推荐的千兆802.11n路由么?
