IP Address對(duì)話框第3步如果預(yù)先知道AP的IP地址和密碼，可在“Remote IP”框中鍵入欲設(shè)置的AP的IP地址，在“Read/Write”框中鍵入有權(quán)限管理該AP的密碼。第6步單擊“確定”按鈕，返回“Enter IP Address”對(duì)話框。圖28 啟用無(wú)線AP的無(wú)線網(wǎng)卡第9步單擊與“ORiNOCO”相對(duì)應(yīng)的“Setup3”按鈕，顯示如圖28所示對(duì)話框。第10步在“Setup”菜單中選擇“SNMP Setup”，顯示如圖29所示“SNMP Setup”對(duì)話框。宣城職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計(jì)論文圖29 SNMP Setup對(duì)話框第11步在“File”菜單中選擇“Save Config”，保存設(shè)置。在訪問(wèn)點(diǎn)無(wú)線網(wǎng)絡(luò)中，無(wú)線站(具有無(wú)線電網(wǎng)絡(luò)卡的設(shè)備，例如便攜式計(jì)算機(jī)或PDA)可連接到無(wú)線訪問(wèn)點(diǎn)。需要注意的是，要自動(dòng)連接到“首選網(wǎng)絡(luò)”列表中沒(méi)有出現(xiàn)的可用網(wǎng)絡(luò)，應(yīng)選中“自動(dòng)連接到非首選網(wǎng)絡(luò)”復(fù)選框。在“無(wú)線網(wǎng)絡(luò)屬性”中，檢查設(shè)置并確保其正確。此外，無(wú)線網(wǎng)絡(luò)就其發(fā)展的歷史來(lái)講，遠(yuǎn)不如有線網(wǎng)絡(luò)長(zhǎng)，其安全理論和解決方案遠(yuǎn)不夠完善。這就使得黑客們有機(jī)可乘。攻擊端電腦只要在無(wú)線路由器/中繼器的有效范圍內(nèi)的話，那么它很大機(jī)會(huì)訪問(wèn)到該無(wú)線網(wǎng)絡(luò)，一旦它能訪問(wèn)該內(nèi)部網(wǎng)絡(luò)時(shí)，該網(wǎng)絡(luò)中所有是傳輸?shù)臄?shù)據(jù)對(duì)他來(lái)說(shuō)都是透明的。通常我們選用能力最強(qiáng)的那種加密技術(shù)。例如linksys設(shè)備的SSID通常是“l(fā)inksys”。最初，這個(gè)功能主要是為那些無(wú)線網(wǎng)絡(luò)客戶端流動(dòng)量特別大的商業(yè)無(wú)線網(wǎng)絡(luò)而設(shè)計(jì)的。（五）設(shè)置MAC地址過(guò)濾眾所周知，基本上每一個(gè)網(wǎng)絡(luò)接點(diǎn)設(shè)備都有一個(gè)獨(dú)一無(wú)二的標(biāo)識(shí)稱之為物理地址或MAC地址，當(dāng)然無(wú)線網(wǎng)絡(luò)設(shè)備也不例外。這導(dǎo)致了另外一個(gè)安全隱患，那就是接入網(wǎng)絡(luò)的攻擊端很容易就通過(guò)DHCP服務(wù)來(lái)得到一個(gè)合法的IP。此外，如果你的鄰居也使用了無(wú)線網(wǎng)絡(luò)，那么你還需要考慮一下你的路由器或中繼器的覆蓋范圍是否會(huì)與鄰居的相重疊，如果重疊的話就會(huì)引起沖突，影響你的網(wǎng)絡(luò)傳輸，一旦發(fā)生這種情況，你就需要為你的路由器或中繼器設(shè)置一個(gè)不同于鄰居網(wǎng)絡(luò)的頻段(也稱Channel)。【致謝】在本論文的寫作過(guò)程中，我的指導(dǎo)老師劉訓(xùn)星傾注了大量的心血，從選題到開(kāi)題報(bào)告，從寫作提綱到一遍又一遍地指出每稿中的具體問(wèn)題，嚴(yán)格把關(guān)，循循善誘，在此我表示衷心感謝。當(dāng)今時(shí)代計(jì)算機(jī)網(wǎng)絡(luò)已經(jīng)在校園中得到廣泛應(yīng)用，并產(chǎn)生了新的教學(xué)方式——數(shù)字化教學(xué)。Abstract: Cable puter network has been in education field have been extensively applied, it to education career has played a very important puter network has been widely applied on campus, and has produced new teaching modedigital recent years, along with the wireless network protocol standards of further perfecting and wireless products ratio of performance to improve, wireless networks gradually into the campus and in the construction of network plays a more and more major role, also play an increasingly important say, wireless network has been widely applied on campus of campus, the students, the teacher also produced great also produced a wireless teaching mode, wireless teaching mode emerges can make wireless network on campus get more extensive ：無(wú)線局域網(wǎng)、校園網(wǎng)、無(wú)線接入站Keywords:
