Lab 9.3.3 Troubleshooting Physical Connectivity

Conclution of this lab activity are:

-  If the wireless client is unable to connect to the AP, it may be because of wireless connectivity problems.
What factors can affect your ability to connect hosts using RF?
a. Not all wireless standards are compatible. The 802.11a (5 GHz band) is not compatible with the
802.11b/g/n standards (2.4 GHz band). Within the 2.4 GHz band, each standard uses different
technology. Unless specifically configured, equipment that conforms to one standard may not function
with that conforming to another.
b. Each wireless conversation must occur on a separate, non-overlapping channel. Some AP devices can
be configured to select the least congested or highest throughput channel. Although automatic settings
work, manual setting of the AP channel provides greater control and may be necessary in some
environments.
c. The strength of an RF signal decreases with distance. If the signal strength is too low, devices will be
unable to reliably associate and move data. The signal may be dropped. The NIC client utility can be
used to display the signal strength and connection quality.
d. RF signals are susceptible to interference from outside sources, including other devices functioning on
the same frequency. A site survey should be used to detect for this.
e. APs share the available bandwidth between devices. As more devices associate with the AP, the
bandwidth for each individual device will decrease causing network performance problems. The solution
is to reduce the number of wireless clients using each channel.
- Modern WLANs incorporate various technologies to help secure the data on the WLAN: incorrect
configuration of any of these can prevent communication. List three.
a. the SSID
b. authentication
c. encryption.

kesimpulan dari lab ini adalah:
- Jika wireless client tidak dapat terhubung ke AP, itu mungkin karena masalah konektivitas nirkabel.Faktor-faktor apa yang dapat mempengaruhi kemampuan Anda untuk terhubung host menggunakan RF?a. Tidak semua standar nirkabel yang kompatibel. The 802.11a (5 GHz) tidak kompatibel dengan
802.11b/g/n standar (2,4 GHz). Dalam pita 2,4 GHz, menggunakan setiap standar yang berbeda
teknologi. Kecuali khusus dikonfigurasi, peralatan yang sesuai dengan satu standar tidak dapat berfungsi
dengan yang sesuai dengan yang lain.
b. Setiap percakapan nirkabel harus terjadi pada saluran yang terpisah, tidak tumpang tindih. Beberapa AP perangkat dapat dikonfigurasi untuk memilih paling padat atau saluran throughput tertinggi. Meskipun pengaturan otomatis kerja, petunjuk pengaturan saluran AP memberikan kontrol yang lebih besar dan mungkin diperlukan dalam beberapa lingkungan.
c. Kekuatan sinyal RF menurun dengan jarak. Jika kekuatan sinyal terlalu rendah, perangkat akan
tidak dapat data andal asosiasi dan bergerak. Sinyal dapat dihapus. Utilitas klien NIC dapat
digunakan untuk menampilkan kekuatan sinyal dan kualitas koneksi.
d. Sinyal RF rentan terhadap gangguan dari sumber luar, termasuk perangkat lain yang berfungsi pada
frekuensi yang sama. Sebuah survei situs harus digunakan untuk mendeteksi untuk ini.
e. AP berbagi bandwidth yang tersedia antar perangkat. Sebagai perangkat lebih diasosiasikan dengan AP,
bandwidth untuk setiap perangkat individu akan menurun menyebabkan masalah kinerja jaringan. Solusinya
adalah untuk mengurangi jumlah klien nirkabel menggunakan setiap saluran.
- Modern WLAN menggabungkan berbagai teknologi untuk membantu mengamankan data pada WLAN: salah konfigurasi salah satu dapat mencegah komunikasi. Daftar tiga.

 a. SSID
b. otentikasi
c. enkripsi.

Lab 9.2.7 Mengatasi Masalah Dalam Jaringan Utilities

   conclution of this Lab are:

-  What type of troubleshooting technique is your best option when troubleshooting wireless networks, wired networks and networks that use both?
A divide-and -conquer technique 

- What do inactive LEDs potently indicate?
a. device failure
b. port failure
c. cabling issues. 
- You are troubleshooting a Linksys ISR. What do the following LED lights indicate?
Solid Green –
Solid green indicates that a device is plugged into the port but no traffic is flowing.
Flashing Green –
Flashing green indicates the device is plugged in and receiving traffic.
Amber –
Amber indicates the device is making adjustments to the way the port is operating.
No Light –
No light indicates that nothing is plugged into the port, or there is an issue with the wired or wireless connection. 
- There are several issues to watch for in cabling. List and explain each.
a. Be sure to use the correct type of cable. Two types of TP cables are commonly encountered in networking: Straight-through cables and Cross-over cables. Using the wrong type of cable may prevent connectivity.
b. Improper cable termination is one of the main problems encountered in networks. To avoid this,cables should be terminated according to standards. Terminate cables via 568A or 568B termination standard Avoid untwisting too much cable during termination Crimp connectors on the cable jacket to provide strain relief
c. Maximum cable run lengths exist based on characteristics of the different cables. Exceeding these run lengths can have a serious negative impact on network performance.
d. If connectivity is a problem, verify that the correct ports are being used between the networking devices.
e. Protect cables and connectors from physical damage. Support cables to prevent strain on connectors  and run cable through areas that will not be in the way.

  Kesimpulan dari lab actifity ini adalah:
- Apa jenis teknik pemecahan masalah merupakan pilihan terbaik anda ketika troubleshooting jaringan nirkabel, kabel jaringan dan jaringan yang menggunakan keduanya?membagi-dan-menaklukkan teknik- Apa yang tidak aktif potently LED menunjukkan?a. kegagalan perangkatb. port kegagalanc. kabel isu.- Anda adalah sebuah masalah ISR Linksys.
