❶ 手機連接上了WLAN後,不能上網是怎麼回事
如果您使用的是華為手機,能連上wifi但是不能上網,可以通過以下方法進行排查處理:
一、若使用的是公共網路:
1.嘗試在人流量較少的地方使用,並確認熱點可正常使用。
2.請確認是否需通過瀏覽器登錄網站注冊後才能上網。
二、若使用的是家庭網路,建議連接其他wifi或手機個人熱點進行測試排查:
1.如果連接其他WiFi正常
(1)請檢查寬頻帳號是否到期,重啟路由器並重啟手機後嘗試;
(2)如果將路由器設置過黑白名單,則需檢查手機mac地址是否加入路由器端,如路由器沒有設置黑白名單,請將路由器斷電重啟嘗試。
2.如果連接其他WiFi也無法上網
(1)請重新打開WLAN開關連接嘗試;
(2)建議在設置中搜索還原網路設置,根據屏幕提示還原。(註:此操作會還原WLAN、移動數據網路和藍牙連接記錄並刪除WLAN和藍牙連接記錄)。
三、若個別應用無法上網:
請打開設置,在上方搜索框內輸入流量管理並點擊進入流量管理頁面,點擊應用聯網 ,查看個別應用是否勾選WLAN許可權,建議將需要使用應用的WLAN許可權全部勾選。
如果嘗試以上方法,均未能解決問題,建議備份數據(QQ、微信等第三方應用需單獨備份),攜帶購機憑證前往華為客戶服務中心檢測。

❷ Tsy一public是什麼無線網路,可以安全地使用嗎
tsy public天山雲寬頻,登錄之後無法安全使用且網速並不理想,不建議使用。並且此無線網路是默認打開無法關閉的,您可以使用移動數據流量或者其他安全可靠的無線網路來連接互聯網。
由於免費WiFi存在路由器和網路漏洞,也成為黑客攻擊的對象,導致網民個人隱私泄露、網銀被盜等案例時有發生。在公共場所接入免費WiFi的安全風險包括用戶的社交軟體賬號、密碼被劫持和惡意利用;手機或電腦中的文件及照片等個人信息泄露;用戶網銀和支付寶等移動支付的資金被盜刷等。
❸ 無線網用英文怎麼寫
無線網的英文是 Wireless network
無線網路的英文:
WiFi (= wireless fidelity)
wifi的意思是無線聯網技術
Wi-Fi is short for wireless fidelity.
Wi-Fi是wireless fidelity的縮寫。
(3)無線網路的安全與隱私的問題英文擴展閱讀:
無線網的應用:
無線網路對世界的重大變革最早可追溯至第二次世界大戰時期。
由於無線網路的應用,消息的傳輸能夠輕易、有效且確實地越洋及越過敵軍戰線。從此,無線網路技術持續發展,地位也越來越重要。
行動電話就是無線網路系統的一部分,人們每天使用行動電話與他人通話。經由利用人造衛星及其他信號,無線網路系統使越洋消息的發送化為可能。
在災難應對上,警局使用無線網路迅速地傳播重要消息;不論是在小型辦公大樓內或橫越整個地球,個人及公司都利用無線網路快速地發送或分享數據。
無線網路的其他重要應用之一,就是在基礎電信建設貧乏或缺乏資源的國家和地區提供一個便宜及快速的管道連接上互聯網,像是大部分的發展中國家。
而在使用無線網路時,兼容性的問題也同時浮現。
不同的製造廠商所生產的組件可能無法在同一個平台使用,或是需要額外的作業程序來使修正這些問題。
基本上無線網路比起經由乙太網電纜直接連線要來的慢。
無線網路比較容易受到攻擊,因為任何人都可以嘗試去入侵無線網路的信號。許多網路提供有線等效加密(WEP)防護系統,但它其實也相當容易受到攻擊。
雖然WEP能夠擋掉一些入侵者,但許多公司基於安全性考量,仍堅持使用有線網路直到問題改善為止。
另一種無線網路防護系統為WPA(Wi-Fi Protected Access)。
WPA提供了比WEP更安全的無線網路環境,而這道防火牆可以幫助易受入侵的無線網路修補漏洞。
❹ 用英文解釋「免費wifi」什麼意思
「免費wifi」The free wifi
Due to the lack of uniform service standards and behavioral norms, the free Wi-Fi market is often overlooked, and the user's use of free Wi-Fi security risks are becoming increasingly prominent. March 15th, CCTV 315 party site exposed the security risk of unsafe WIFI network, hackers can steal the party through the construction of fake WIFI network of mobile phone system, brand model, self photos, email account password and other privacy data.
2015, the security of free WiFi plus the user protection plan to protect the user's rights and interests, the application of treasure free WiFi to become an important channel for free internet access to users.
由於免費Wi-Fi市場目前缺少統一的服務標准和行為簡伍規范,基礎安全能力往往攔轎或被忽視,而用戶使用免費Wi-Fi的安全隱患日益凸顯。3月15日,央視315晚會現場曝光了不安全WIFI網路的安全風險——黑客可以通過構造假的WIFI網帆臘絡盜取晚會現場觀眾手機系統、品牌型號、自拍照片、郵箱帳號密碼等各類隱私數據。
2015年,安全的免費WiFi 加上「用戶保障計劃」全面保護用戶支付權益,應用寶免費WiFi成為用戶免費安全上網的重要渠道。
❺ 手機WIFI的時候旁邊顯示一個感嘆號什麼意思
表示手機能夠連上Wi-Fi,但是目前有故障導致無法通過這個Wi-Fi連接到互聯網;可以通過排除法查看是手機還是WiFi的問題。以下是相關的解決方法介紹:
1、手機Wi-Fi的時候旁邊顯示一個感嘆號代表手機連上Wi-Fi但無網路訪問;
2、這可能是由於WiFi本身就是出現網路連接問題,能夠正常連接設備但是沒有正確接入到互聯網;
3、如果是其他設備能夠正常連接,可能是由於該WiFi開啟了連接設置,限制了您當前設備的連接訪問。
(5)無線網路的安全與隱私的問題英文擴展閱讀:
解決方法:
1、若無法連接中文名稱的無線網路:
由於設備兼容性問題,部分中文名稱或特殊符號的無線網路可能無法連接,建議將無線網路名稱改為英文。
2、若出現搜索不到或報錯、超時等情況:
請檢查路由器連接是否正常(無法連接貓),將手機和路由器關機重啟後再連接嘗試。
3、若以上操作均無效,建議備份重要數據(聯系人、簡訊、照片等),恢復出廠設置嘗試。
若問題依然存在,請您攜帶購機發票、包修卡和機器送到三星服務中心檢查。
❻ 手機無線總連不上網怎麼辦啊
若使用vivo手機,指手機連接WiFi正常但不能上網,可以查看以下內容:
1、查看手機設置
進入設置--WLAN,查看是否已成功連接WiFi。
進入設置--其他網路與連接--私人DNS,查看是否設置了私人DNS,如有開啟,建議將私人DNS設置為關閉再重試。
進入設置--安全/安全與隱私--更多安散褲全設置--受信任的憑據--系統--請將所有選項打開。
2、排查WiFi
請對比其它手機連接相同WiFi是否正常,確認是WiFi還是手機原因。如是WiFi原因,請重啟無線路由器查看。部分公共WiFi需要通過瀏覽器認證後才能聯網。
3、查看聯網許可權
請進入i管家--流量管理/流量監控--聯網管理--WLAN--開啟軟體聯網許可權。
4、排查環境原因
如果手機距離路由器較遠,雖然顯示有WiFi信號,但實際可能無法上網,建議調整手機與路由器之間的距離後再嘗試。
5、重置網路設置
做好WiFi等資料備份,進入設置--系統管理--備份與重置--重置網路設置--重置設置,再使用查看飢拆。
註:重置網路設置會清除WLAN、移動數據網路、藍牙等連接記錄;雙卡時需選擇對應的SIM卡。
6、還原所有設置(查看不到重置網路設置菜單時,進行此操作)
進入設置--系統管理/更多設置--備份與重置--還原所有設置,根據屏幕提示操作。
註:此操作不會刪除軟體或文件,僅會重置所有的設置選項;為了數據安全,操作前可沖肢簡以備份好重要數據。
7、服務中心檢測
若以上方法未能解決問題,請提前備份好手機數據,攜帶手機和購機憑證前往vivo客戶服務中心檢測。可以通過此鏈接:網頁鏈接查詢到最近的客戶服務中心地址及電話。為節省寶貴時間,建議提前致電客戶服務中心,確認相關事宜和了解上班時間。
❼ WLAN風險提示<unknown ssid>存在安全風險,可能導致隱私信息泄露。是否斷開該網路
最好設置下絕亮無線路由器登春亮錄密並森寬碼,無線網路加密方式選擇WPA2-PSK,並設置好密碼。你連接的WIFI應該是沒有加密的吧。

關於安全的英語作文
人的生命只有一次,所以遵守安全規則是必不可少的,其中最容易被人們忽視,而又最重要的就是交通安全。
在科技發達的今天,豪華的轎車已經進入千家萬戶的時候,可怕的交通事故也隨之而來。
據調查中國每年死於交通事故人數有十萬左右,其中中小學生就佔了12%,這些數字足以表明災難的可怕性,看了真讓人膽戰心驚。
記得,報紙上報道過:在2005年1月24日,發生了一起嚴重的交通事故,原因是因為司機亂闖紅燈。
那天,大雪紛飛,本來就很滑的道路上還結了一層薄薄的冰,車輛排成了一個很長的隊伍。
綠燈顯示馬上再過2秒鍾即將變為紅燈,但是不知從哪裡突然躥出了一輛黑色轎車,跑到十字馬路中間的時候,另一個方向是綠燈,第一排的麵包車司機也非常抓緊時間,可怕誤了一分一秒地向前沖去,正好與剛要轉彎的黑色小轎車撞了個正著。
隨後的車輛也因路滑而沒有剎住車,造成了嚴重交通事故。
只聽見「砰、砰」的幾聲響,四五輛車都堆到了一起。
有的車玻璃和倒車鏡被撞碎,嚴重的有輪胎被撞掉,車頭被撞歪,還冒起了微微的輕煙。
這起交通事故雖然沒有人員死亡,卻有很多人都受了傷,其中小轎車的司機可能會導致終身癱瘓……這起事故充分的說明了闖紅燈的危險性,不怕一萬,只怕萬一,「紅燈停,綠燈行」這是誰不知道的呢?何必為了爭取那麼一點時間而來冒這種危險,這種生死一線的事情,自己心裡都是最清楚後果。
哪怕是多等一分鍾,等到綠燈亮了,我們再走,這就保證了我們的生命安全。
遵守交通安全要從我們小學生開始做起,人人都應當做到,這樣既保護了我們的生命,又減少了國家的財產損失,我們應該把交通安全牢記在心,真正做到一路平安。

Automobile,the most pervasive and persuasive of modern technologies,marked by rapid change and growth ,is moving into a new era,an era of extraordinary sophistication and versatility, which promises to reshape our lives and our world.Discussion on the ality has bee very popular in newspapers or in people's chats. On the one hand, no one denies that automobile is currently one of the most useful transportation in our daily life. On the other hand, the automobile is more of a trouble as its abundance results in frequent traffic jams. The harm and loss they cost are incalculable. Heavy traffic will make much time waste for nothing and accidents happen form time to time. In addition, more and more private cars will make environmental pollution more serious, which will do harm to human beings.In my opinion, it is high time for the whole people to rece the frequency of traffic jams. The first step should be to fundamentally chane lifestyles so that the car is no longer part and parcel of everyday life. Governments also need to apply attractive measures to draw citizens to adopt means of public transportation, for instance, to rece prices and improve relevant facilities.汽車,最普及和最有影響力的現代技術,以快速變化和發展為標志,正在步入一個新時代,一個極為成熟和多樣化的時期,這將重塑我們的生活和我們的世界。

❾ 無線網路面臨哪些安全威脅
無線網路安全並不是一個獨立的問題,企業需要認識到應該在幾條戰線上對付攻擊者,但有許多威脅是無線網路所獨有的,下面是學習啦小編整理的一些關於無線網路存在的威脅的相關資料,供你參考。
企業無線網路所面臨的安全威脅
1、插入攻擊
插入攻擊以部署非授權的設備或創建新的無線網路為基礎,這種部署或創建往往沒有經過安全過程或安全檢查。可對接入點進行配置,要求客戶端接入時輸入口令。如果沒有口令,入侵者就可以通過啟用一個無線客戶端與接入點通信,從而連接到內部網路。但有些接入點要求的所有客戶端的訪問口令竟然完全相同。這是很危險的。
2、漫遊攻擊者
攻擊者沒有必要在物理上位於企業建築物內部,他們可以使用網路掃描器,如Netstumbler等工具。可以在移動的交通工具上用筆記本電腦或其它移動設備嗅探出無線網路,這種活動稱為「wardriving 」 ; 走在大街上或通過企業網站執行同樣的任務,這稱為「warwalking」。
3、欺詐性接入點
所謂欺詐性接入點是指在未獲得無線網路所有者的許可或知曉的情況下,就設置或存在的接入點。一些雇員有時安裝欺詐性接入點,其目的是為了避開公司已安裝的安全手段,創建隱蔽的無線網路。這種秘密網路雖然基本上無害,但它卻可以構造出一個無保護措施的網路,並進而充當了入侵者進入企業網路的開放門戶。
4、雙面惡魔攻擊
這種攻擊有時也被稱為「無線釣魚」,雙面惡魔其實就是一個以鄰近的網路名稱隱藏起來的欺詐性接入點。雙面惡魔等待著一些盲目信任的用戶進入錯誤的接入點,然後竊取個別網路的數據或攻擊計算機。
5、竊取網路資
有些用戶喜歡從鄰近的無線網路訪問互聯網,即使他們沒有什麼惡意企圖,但仍會佔用大量的網路帶寬,嚴重影響網路性能。而更多的不速之客會利用這種連接從公司范圍內發送郵件,或下載盜版內容,這會產生一些法律問題。
6、對無線通信的劫持和監視
正如在有線網路中一樣,劫持和監視通過無線網路的網路通信是完全可能的。它包括兩種情況,一是無線數據包分析,即熟練的攻擊者用類似於有線網路的技術捕獲無線通信。其中有許多工具可以捕獲連接會話的最初部分,而其數據一般會包含用戶名和口令。攻擊者然後就可以用所捕獲的信息來冒稱一個合法用戶,並劫持用戶會話和執行一些非授權的命令等。第二種情況是廣播包監視,這種監視依賴於集線器,所以很少見。
當然,還有其它一些威脅,如客戶端對客戶端的攻擊(包括拒絕服務攻擊)、干擾、對加密系統的攻擊、錯誤的配置等,這都屬於可給無線網路帶來風險的因素。
(1)加密密文頻繁被破早已不再安全
曾幾何時無線通訊最牢靠的安全方式就是針對無線通訊數據進行加密,加密方式種類也很多,從最基本的WEP加密到WPA加密。然而這些加密方式被陸續破解,首先是WEP加密技術被黑客在幾分鍾內破解;繼而在11月國外研究員將WPA加密方式中TKIP演算法逆向還原出明文。
WEP與WPA加密都被破解,這樣就使得無線通訊只能夠通過自己建立Radius驗證伺服器或使用WPA2來提高通訊安全了。不過WPA2並不是所有設備都支持的。
(2)無線數據sniffer讓無線通訊毫無隱私
另一個讓用戶最不放心的就是由於無線通訊的靈活性,只要有信號的地方入侵者就一定可以通過專業無線數據sniffer類工具嗅探出無線通訊數據包的內容,不管是加密的還是沒有加密的,藉助其他手段都可以查看到具體的通訊數據內容。像隱藏SSID信息,修改信號發射頻段等方法在無線數據sniffer工具面前都無濟於事。
然而從根本上杜絕無線sniffer又不太現實,畢竟信號覆蓋范圍廣泛是無線網路的一大特色。所以說無線數據sniffer讓無線通訊毫無隱私是其先天不安全的一個主要體現。
(3)修改MAC地址讓過濾功能形同虛設
雖然無線網路應用方面提供了諸如MAC地址過濾的功能,很多用戶也確實使用該功能保護無線網路安全,但是由於MAC地址是可以隨意修改的,通過注冊表或網卡屬性都可以偽造MAC地址信息。所以當通過無線數據sniffer工具查找到有訪問許可權MAC地址通訊信息後,就可以將非法入侵主機的MAC地址進行偽造,從而讓MAC地址過濾功能形同虛設。
